The TempLS analysis, based on GHCNV3 land temperatures and the ERSST sea temps, showed a monthly average of 0.53°C for May, unchanged from April (April rose by a few thousandths with late data). UAH also was virtually unchanged. It was still very warm in much of NH, including the Eastern USA. There are more details at the latest temperature data page.
Below is the graph (lat/lon) of temperature distribution for May.
This is done with the GISS colors and temperature intervals, and as usual I'll post a comparison when GISS comes out.
And here, from the data page, is the plot of the major indices for the last four months:

So how hard would it be to generate a version of your code that did say, seven-day averages instead of monthly?
ReplyDeleteCarrick,
ReplyDeleteNot vary hard - a month could be defined as 7 days. A little trouble about fractions. But the problem would be to get station data at that frequency. There is GHCN Daily, but I don't know how up to date it is kept.
It'd be interesting to look at what the data give first, to see whether it's worth the extra hassle of daily updates.
ReplyDeleteDaily station data is in principle available, although I'm not sure how timely outside US. But the damper is SST. That does come out two or three times a month, but I don't think there's part-month data - the later versions are just updates of the same month (I think).
DeleteArgo updates daily. So in principle, one could have a daily series since that started, at least.

ReplyDeleteUpdated mondays.
Thanks. Well, it's an interesting idea. This site shows weekly station temps, fairly up to date from SYNOP data, so it looks possible. And the computation at my end is not too demanding. I'll check.
DeleteOf course, it would be noisy.
OT - May is up:

Not really OT - but even less is that GISS is also out - up 0.1C. I'll do my usual comparison post. The NOAA number doesn't seem to be in the online data yet, so it isn't showing in the ice and temp page.
DeleteThe big news there though is the ice melt. It's gone very quickly, and is in Jaxa at a record low for this time of year. That may not last - the Jaxa pattern since resuming is a huge drop reported every day, adjusted up a few hours later. But recently, the adjustments have been less.
