Climate data postings


For a couple of years I've been running a daily script to track new monthly temperature indices and also sea ice data. The script posts them on the data page.

I'm upgrading this - I now use wget to monitor the data sites. A by-product is that I have a listing of the times as posted by the source, and I thought I could add that to the site, newest first. I've put that table at the head of the list on the data page. Time zone is US Eastern (eg NY). Here's how it looks at the moment:

DateNameSize KbSource
Nov 22 08:56 GHCN V3 station temps 12196 source
Nov 20 13:53 HadCRUT 4 land/sea temp anomaly 209 source
Nov 20 00:59 NOAA land/sea temp anomaly 29 source
Nov 19 15:42 GISS land/sea temp anomaly 16 source
Nov 18 00:06 HADSST2 mean 4145 source
Nov 18 00:05 CRUTEM CRU global mean Station anomaly 30 source
Nov 09 07:48 UAH lower trop anomaly 65 source
Nov 05 12:58 RSS-MSU Lower trop anomaly 37 source
Nov 04 21:21 ERSST NOAA SST grid 3274 source

Indices are in black - spatial data (large) in brown. I can fairly easily add new sources to the list. I've chosen one representative file from each source, expecting that others of interest are likely to be posted at the same time. The list will be maintained on the data page. I also plan to post a history file (when there is some history). Some sources like GISS update their monthly postings frequently, so the date you see here may not be the first posting for the month.
