GISS Surface Temperature Analysis

Station Data: GHCN v3 and SCAR

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_v3'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

  1. the number of stations with record length at least N years as a function of N ,
  2. the number of reporting stations as a function of time,
  3. 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.

We also provide access to the last release that was based on GHCN version 2 data. It is an archive of the GISTEMP station record from Nov 2011 when we discontinued the use of NCDCs GHCNv2 dataset and is provided only as a historical facility. The differences between this station data set and our current station dataset are due to the switch from GHCN v2 to GHCN v3.2, and the reliance on NCDC homogenizations of station data instead of our own original methodology. For details, please see the FAQ

You may also download all GISS homogenized station data as a text or csv file.

The available stations are marked on the globe below. You may select the type of records (unadjusted, NCEI adjusted, cleaned, homogenized); you may also limit the marked stations to the ones whose records start on or before the month entered in the “From” box, and whose records end on or after the month entered in the “To” box. A count of the matching stations is provided (after clicking on “Update”). If the From/To boxes are void, all stations of the selected type are marked.

You may rotate the globe and zoom in or out. The "Reset" button only resets the zooming. Hovering over a station's dot will display some station information; clicking on it will produce an annual mean graph of the selected station and give access to the station data. The graphs of all record types are shown; however, only the data of the selected type are provided in tabular form.

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 four seasons (Dec-Nov mean). For a description of how the seasonal and annual means are computed, click here.

When viewing an individual station's data, use the “Get Neighbors” button to obtain a list of neighbor stations of the selected type, independent of the From/To selection. It may be used to get to stations obscured on the selection globe below.

You may also select stations by name or location using the form at the bottom of this page.
