IRI/LDEO Climate Data Library

The IRI/LDEO Climate Data Library contains over 300 datasets from a variety of earth science disciplines and climate-related topics. It is a powerful tool that offers the following capabilities at no cost to the user:

access any number of datasets;
create analyses of data ranging from simple averaging to more advanced EOF analyses;
monitor present climate conditions with maps and analyses in the Maproom;
create visual representations of data, including animations;
download data in a variety of commonly-used formats, including GIS-compatible formats.

New Datasets and Features

CPC GHCN-CAMS global monthly gridded land-only surface air temperature

The Climate Prediction Center's GHCN-CAMS global monthly gridded (0.5 degree lat./lon. resolution) land-only surface air temperature data set has been added. It includes monthly surface air temperature data from January 1948 to the present and is updated in real time. This product is an analysis based upon station data from both the Global Historical Climatology Network version 2 (GHCN) and the Climate Anomaly Monitoring System (CAMS).

NASA GPCP Version 2.1 monthly precipitation dataset has been added

The latest version (version 2.1) of NASA's Global Precipitation Climatology Project (GPCP) monthly precipitation data set has been added to the Data Library. The product includes multiple estimated precipitation variables and error estimates derived from various combinations of IR and microwave satellite and gauge observations. The satellite-gauge product is updated from time to time with more recent observations.

average now has a /keepgrids option

The average operator normally removes each independent variable that is averaged over, so that, for example, a mean can easily be removed from an entire time series. But there is now a /keepgrids option, which keeps the independent variable as a single point grid. This is most useful for downloading to software that insists on a time grid.
