NOAA Climate Data Records (CDRs)


NOAA’s Climate Data Records (CDRs) are robust, sustainable, and scientifically sound climate records that provide trustworthy information on how, where, and to what extent the land, oceans, atmosphere, and ice sheets are changing. NOAA CDRs are vetted using standards established by the National Research Council (NRC). Climate Data Records are created by merging data from surface, atmosphere, and space-based systems across decades. This process allows analysis of the underlying climate trends within the data and permits users to identify economic and scientific value in these records. The National Centers for Environmental Information (NCEI) maintains and extends CDRs by applying the same methods to present-day satellite measurements.

CDRs vary in the time period they represent, but each CDR has an earliest date between 1979 and 2000.

CDRs are broken into four categories:

This dataset is available on Azure thanks to the NOAA Big Data Program.

Storage resources

Data are stored in NetCDF format; each CDR is in an individual blob container in the following storage account:

NetCDF structure and file naming conventions vary slightly across data sets; see below for documentation of individual CDRs, along with links to their original documentation. However, most CDRs use one of the following naming conventions:[product]/data/[year]/[filename].nc[product]/data/[year]/[month]/[filename].nc

product is a short name for one of the CDRs, and also specifies the blob container name. A list of products and their associated container names is below.

For example, the following NetCDF file contains information from the “Leaf Area Index” (leaf-area-index-fapar) product for January 1st, 2003:

The highlighted text indicates the date, and occurs in most NetCDF file names.

Available products

Parentheses indicate product short names, which correspond to container names as per above.

Region information

Large-scale processing is best performed in the East US Azure region, where the data are
