Detailed Description:
-
The merged land air and sea surface temperature anomaly analysis is based on data from the Global Historical Climatology Network (GHCN)
of land temperatures and the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) of Sea Surface Temperature (SST) data.
Temperature anomalies with respect to 1961-1990 are analyzed separately. The analyzed monthly temperature anomalies are
then merged to form the global analysis. More dataset information can be found at NCDC's Global Surface Temperature Anomaly webpage. This is the dataset NOAA uses for global temperature monitoring.

Caveats:
- Older data changes slightly each month, particularly near the present so you shouel note the date the file was obtained (in the file metadata).

- Please note: If you acquire NOAA Merged Air Land and SST Anomalies data products from PSD, we ask that you acknowledge us in your use of the data. This may be done by including text such as NOAA Merged Air Land and SST Anomalies data provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at http://www.esrl.noaa.gov/psd/ in any documents or publications using these data. We would also appreciate receiving a copy of the relevant publications. This will help PSD to justify keeping the NOAA Merged Air Land and SST Anomalies data set freely available online in the future. Thank you!
