September global surface TempLS down 0.073°C from August.

The TempLS FEM anomaly (1961-90 base) was 1.186°C in September, down from 1.259°C in August. It was the second warmest September in the record, just behind 2023.

I'm sorry the posting is so late this month.Again, GHCN has been erratic. It started well, but for several days following 2 October, there simply were no postings at all. Then there was gradual increase, but for many days now, the number of stations outside US (the limiting factor) has been stuck at about 2670. Last month we passed 3000 stations on the 9th. I've been waiting for a big new update. Still, 2670 is not bad, so I'm reasonably confident, and this month GISS has come out earlier, with similar results.

August global surface TempLS up 0.136°C from July.

The TempLS FEM anomaly (1961-90 base) was 1.241°C in August, up from 1.105°C in July. It was the warmest August in the record, by a fair margin, and with last month the warmest July, it seems the El Niño is really stirring. 2026 is already second in terms of annual to date, and has an excellent chance of overtaking 2024.

I have been complaining of erratic posting by GHCN, but this month was fairly smooth, and there are now over 3000 statins outside USA.

July global surface TempLS up 0.045°C from June.

The TempLS FEM anomaly (1961-90 base) was 1.097°C in July, up from 1.052°C in June. It was the warmest July in the record, just ahead of 2023.

Once again there were difficulties with GHCN data posting. GHCN usually posts a single gz file, named ghcnm.tavg.latest.qcu.tar.gz, which should contain the latest files, with names including the date. That is good for scripting when it works, with a constant url for the package. But last month, I found that new such files were posted, but with old data. So I switched to another archive directory where files had the date in their names, and seemed to be more up to date.

But early this month, the archive was not getting new files, and the old system was better. I found also a directory called access which seemed ideal - it has the latest files, dated, but uncompressed. However, eventually the archive caught up, and meanwhile the access directory vanished. However, the number of non-US stations, which is my test, has stalled at about 2700, whereas last month it went fairly quickly to 3200 Still, 2700 isn't bad, so I'll post.

June global surface TempLS up 0.062°C from May.

The TempLS FEM anomaly (1961-90 base) was 1.038°C in June, up from 0.976°C in May. It was the second warmest June in the record after 2024.

Results are late this month. The main reason is again GHCN. I normally download a file called ghcn4.tavg.latest.qcu.tar.gz, which untars to give a directory with data, all with a date in the name. Usually it is the latest, with sometimes a day or two lag. But on July 3, it stopped updating. The wrapper file showed a new date, but the names on the contents remained July 3, and the file contents didn't change. There were only 1176 stations outside the US, so I couldn't post.

The wrapper is useful, because I don't have to keep updating the URL. However, I found the archive which had the actual date-named files, and they were up to date.So I downloaded the latest one. I made an error which led, for a while, to me still using a copy of the old data, but when I had fixed that, the new file had over 3000 stations outside US - good to go. I'll have to cope with the need to update the URL.

On blog matters, I've been updating the mechanics of the latest data page, so things sometimes were not showing properly. Nearly finished now, I think.

May global surface TempLS down 0.04°C from April.

The TempLS FEM anomaly (1961-90 base) was 0.962°C in May, down from 1.002°C in April. It was the second warmest May in the record, behind 2024.

It is a bumpy ride with GHCN V4 lately. The file posted on May 30 was empty, and then nothing postd until June 4. At first there were few stations outside USA, but then there was a big jump to over 3000, high by recent standards.
