2019 sea ice area and extent data

[sja45uk]

There are many different ways to look at change is sea ice. Each gives a different view. Examples attached are looking at open water percentages instead of sea ice area. Still under development.

Love these charts. It is interesting to see the jump up for the CAB in 2007 when so much MYI met its demise. The % of open sea has been higher since.

Chukchi as well.

Not sure what I am seeing here, running 30-day averages as it is clearly filtered?

Hi Killian,
sorry you had a typo

"Daily Changes Needed to Exceed 2012 low on Oct. 10. (Related to effect of GAC and it's import vs. 2019's melt cycle.)"

Oct. 10 should almost certainly be Aug. 10.

You might want to edit your post.

No filters.

If the label says it is for a month's period it is based on that month's average of daily sea ice area readings,
If the label says it is for a three month period it is based on those three month's average of daily sea ice area readings,

The formula is simply ...
open water percentage = (the physical area of that sea minus the average daily ice area in that period) divided by the the physical area of that sea as a %.

Daily Change to Exceed 2012 Record Daily Lows

7/31/2019 = -40k
                = 5.96M km sq., a record low for the date.

8/01/2012 = 6.08M km sq.
7/31/2019 = Loss of < 120k km sq. required for a record low on this date.

Shouldn't that be a gain of < 120k km sq?

Semimonthly BOE evaluation

July 31 extent was 5,955,851 km^2. With on average 44 days to go until the end of the melt season on September 13th, we now require a daily drop of -112,633 km^2 for a BOE to occur. (See Attachment 1).

Total extent loss in July 2019 was -3,080,630 km^2. And total extent loss so far this season is -8,315,270 km^2. This has resulted in the current average daily drop of -58,974 km^2. For the period from maximum to July 31st, this is the 3rd fastest rate of melt for the same period for the years 2007-2019. Barely squeaking in behind 2012, and lagging well behind 2010. (See Attachment 2). 
Additionally, if the melt season ended today, -58,974 km^2 would place 2019 as 3rd out of 13 for the years 2007-2019, once again behind 2010, with 2012 in first place.

Looking only at the month of July, we have averaged -99,375 km^2 per day. This average daily drop places July 2019 as 2nd out of 13 (2007-2019) in average daily July melt. We needed a drop larger than 58k today to maintain 1st place in this category. (See Attachment 3).

[Ktb]

And for comparisons to other years:

The following attachment is for actual previous years daily average melt from August 1 to their respective minimums. From this point until the end of the melt season, only 3 years since 2007 have maintained greater than -60,000 km^2/day losses. (Attachment 1).

The following section is for what the previous years would have needed for a BOE to occur: From August 1st to each years respective minimum, our current BOE requirement is the 4th highest value, of which 2018 is the leader. Keep in mind that 2018's minimum was reached on September 21st. (See attachment 2).

- Area loss 72 k, 13 k MORE than the 2010's average loss of 59 k on this day.
- Total area 2nd Lowest, 63 k LESS than 2016, and 125 k MORE than 2012.

Outlook
We are now in the period of reducing daily area loss that that will slide to zero by mid-September.
On this day area loss perked up, but not as much as in 2016 and 2012.

Of note were:
- The Chukchi & the ESS continue to lose area at a good clip,
- The Beaufort is showing greater signs of ice melt,
- The CAA should be really warm all this week - and some rain. Also increasing daily melt.
- No Fram export - Greenland area loss accelerating.
- the CAB had an area loss for a 2nd day.

The final area outcome - ??

Makes one think.

Makes one think that the only difference is the extra ice near Svalbard, ice that does not have CAB characteristics and is relatively easy to melt. Other differences in 2012's favor are Beaufort ice (will melt eventually), Laptev (will melt), and western CAA (this could be the important lead). In 2019's favor is the ESS/Chukchi, hard to melt ice, but it did melt in 2012 anyway.

The ESS does not look hard to me, and there is alternate storm/compaction/storm in the next 15 days probably. It should not withstand.... No?

Gerontocrat was talking about area, not extent.  It's not just the extra ice near Svalbard.  Most of the CAB looks "whiter" in 2019 than in years like 2012 or 2016 for the NSIDC sea ice concentration images.  Comparison 2019 vs. 2012:

JAXA ARCTIC EXTENT :- 5,905,215 km2（August 1, 2019）

JAXA extent loss continues at a slow rate.

- Extent is lowest in the satellite record (45 days this year), extent is 177 k below 2012, 417 k below 2016.
- Extent loss on this day 51 k, 13 k LESS than the average loss on this day of 64 k.
- Extent loss from maximum 8,366 k, 552 k (7.1%) greater than the average of 7,814 k loss from maximum by this day,
- On average 79.1% of the melting season done, with 43 days to average date of minimum (13 September).

The Perils of Projections.
**Average remaining melt would give a minimum of 3.84 million km2, 2nd lowest in the satellite record, 0.66 million km2 above the 2012 low of 3.18 million km2 and 0.18 million below the 2nd lowest  in 2016 of 4.02 million km2.

Ice Melt Outlook The peak days of daily melt are past. From now to minimum, on average daily extent loss will gradually reduce until the minimum. 

Over the next 5 days Greenland, Baffin Bay and the CAA will still be warm, and at times hot. The CAA may well get some rain. And once again it looks like there will be little or no export of ice down the Fram into the Greenland Sea, though on the Russian side winds may tend to push ice into the Barents. Persistent but not strong easterlies across the north of Greenland and the CAA?

JAXA ARCTIC EXTENT :- 5,785,444 km2（August 3, 2019）

JAXA extent loss continues at a slowly increasing rate.

- Extent is lowest in the satellite record (47 days this year),
- extent is 125 k below 2012, 299 k below 2016.
- Extent loss on this day 67 k, 16 k LESS than the average loss on this day of 83 k.

- On average 80.6% of the melting season done, with 41 days to average date of minimum (13 September).

The Perils of Projections.
**Average remaining melt would give a minimum of 3.87 million km2, 2nd lowest in the satellite record, 0.69 million km2 above the 2012 low of 3.18 million km2 and 0.15 million below the 2nd lowest  in 2016 of 4.02 million km2.

Ice Melt Outlook The peak days of daily melt are past. From now to minimum, on average daily extent loss will gradually reduce until the minimum. 

Little change in the 5 day weather outlook maps from GFS...
On the Russian side winds may continue tend to push ice into the Barents, while central Siberia looks very warm.
Greenland, Baffin Bay and the CAA will still be warm. The CAA may well get some rain.
And once again it looks like there will be little or no export of ice down the Fram into the Greenland Sea.

[Killian]

Whatever Okhotsk does , we are heading under 4 million sqkm today , already below the 2000's average minimum and still on track for 1st

Not really. I'm betting 2019 ASIE is higher than 2012 ASIE by the 7th (JAXA). If that happens, '19 will have a very hard time catching 2012 again and staying ahead. Average melt is just too low as the season progresses.

The key is whether, as some are forecasting, there's a big melt out of all that mush at the perimeter westerly and northerly of the central area of the basin.

I just had a look at geronotcrat's 31.07.2018 values of these three seas that do not have any ice left:
4.796 km² Okhotsk, 2.514 km² St. Lawrence, 2.595 km² Bering.
Obviously there is no ice any more, but the sensors seem to identify some. With around 4 M km² ice area, it is way less than 1%, so it does not matter in the whole picture.

NSIDC daily area is currently second lowest for the date, behind 2012.  There were strong losses this week.

Sometimes the sensors get fooled, usually at similar places, especially on the shoreline.

But sometimes even the AMSR2 sensor (much sharper than the NSIDC sensor) gets caught out with new virtual ice. Observe the Aug 2 & Aug 3 image extracted from Univ Bremen attached.

NSIDC Total Area as at 3 August 2019 (5 day trailing average)  3,911,453 km2

The turnaround continues for a fifth day.
Area loss well above average.

- Area loss 104 k, 33 k MORE than the 2010's average loss of 71 k on this day.
- Total area 2nd Lowest, 105 k LESS than 2016, and 152 k MORE than 2012.

Outlook
We are now in the period of reducing daily area loss that that will slide to zero by mid-September.
On this day area loss perked up again, more than in 2016 and as much as in 2012 on this day.

Of note is:
- All the seven seas of the High Arctic are losing seas ice area at above average daily rates.
- The Chukchi & the ESS continue to lose area at a good clip,
- The Beaufort is showing increased ice melt,
- The CAA should be really warm all this week - and some rain. Also increasing daily melt.
- No Fram export - but Greenland area loss slowed.
- the CAB had a much larger area loss for a 4th day.

Area continues 'twixt 2012 and 2016.

Not really. I'm betting 2019 ASIE is higher than 2012 ASIE by the 7th (JAXA).

Going out on the limb there.

NSIDC Total Area as at 3 August 2019 (5 day trailing average)  3,911,453 km2

Herewith an analysis of NSIDC 5 day area using same basis as the JAXA extent analysis.

NSIDC sea ice area loss continues at a well above average rate.

- Extent is 2nd lowest in the satellite record,
- Extent loss from maximum 9,212 k, 514 k (5.9%) greater than the average of 8,697 k loss from maximum by this day,
- On average 86.8% of sea ice area loss done, with 41 days to average date of minimum (13 September).

The Perils of Projections.
Average remaining melt would give a minimum of 2.59 million km2, 3rd lowest in the satellite record, 0.34 million km2 above the 2012 low of 2.25 million km2 and 0.14 million above the 2nd lowest  in 2016 of 2.45 million km2.

Ice Melt Outlook The peak days of daily melt are past. From now to minimum, on average daily area loss will gradually reduce until the minimum. 

Little change in the 5 day weather outlook maps from GFS...
On the Russian side winds may continue tend to push ice into the Barents, while central Siberia looks very warm.
Greenland, Baffin Bay and the CAA will still be warm. The CAA may well get some rain.
And once again it looks like there will be little or no export of ice down the Fram into the Greenland Sea.

ps: Graph of total arctic sea ice area already posted earlier, so here is the 365 day trailing average graph since 1990. Still some way to go to get to new lows - blame 2018.

Not really. I'm betting 2019 ASIE is higher than 2012 ASIE by the 7th (JAXA).

Going out on the limb there. 

With all the slush and the cyclones blowing through, I think so. We could easily see multiple days of 100k drops... or one huge drop... or the ice just sort of keep hanging on as it has. Not easy call, is it? After all, wouldn't everyone be doing it?

[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

August 4^th, 2019:
     5,719,542 km², a drop of -65,902 km².
     2019 is the lowest on record.
     (2012 highlighted).

[Jontenoy]

Extent is 5.72 M sq km and area 3.90 M sq km. Therefore 1.82 is the water area of the 5.72
This represents 32 % of the 5.72 M sq km and so could be a measure of the slushiness of the total ice pack
