GISS Surface Temperature Analysis
Station Data Based on GHCN v2, Ending in Oct 2011
In our analysis, we can only use stations with reasonably long, consistently measured time records. This is a subset of the full list of stations (copied from GHCN's website and augmented from SCAR). That subset of list of stations that contribute to the final products may slightly change with each update, as the number of stations that get dropped due to the shortness of their temperature record may decrease when new data are added.
The figures below indicate
- the number of stations with record length at least N years as a function of N ,
- the number of reporting stations as a function of time,
- the percent of hemispheric area located within 1200km of a reporting station.
Data and graphs for the individual stations can be downloaded using the form below.

Note: In the tables, DJF, the Northern Hemisphere Winter mean, uses the December of the previous year, and so does metANN, the "meteorological annual mean", i.e. the mean over the 4 seasons (Dec-Nov mean). For a description of how the seasonal and annual means are computed, read on..
