Integrated Surface Database


ISD-Lite is a data product derived from the full Integrated Surface Data (ISD) with the goal of making ISD easier to work with for general research and scientific purposes. It is a subset of the full ISD containing eight common surface parameters in a fixed-width format free of duplicate values, sub-hourly data and complicated flags.

Access to ISD-Lite is currently available only via FTP in compressed ASCII format. Free access is restricted to .edu, .gov and .mil domains. Other domains can access ISD-Lite data with subscription to the full ISD FTP Site. For more information on access and subscriptions to ISD and ISD-Lite, please see the NCDC Online Data Access Policy site.
