>RDA data web download, subset, and format conversion request processing services continue to be unavailable due to ongoing maintenance of the data storage system. Please use the Globus Download option to transfer files from completed online data requests and to attempt to transfer files from dataset archives. There is currently no ETA on when the data storage system will return to production. We will provide any updates on our blog page if new information becomes available.

 Look for Data
A quantity that is measured, computed, or derived (e.g. - temperature, precipitation amount, etc.)
The type of data values - e.g. grid (interpolated or computed gridpoints), platform observation (in-situ or remotely sensed measurements, etc.
The time distance between discrete observation measurements, model product valid times, etc. A time resolution of "Hourly to < Daily" means data that occurs more often than once per day but no more often than once per hour.
The entity that acquired or computed the data (e.g. - aircraft, land station, reanalysis model)
The horizontal distance between discrete gridpoints, stations, measurements, etc.
Topic and subtopic are high-level groupings of parameters (e.g. - Atmosphere (topic), Clouds (subtopic of Atmosphere) ).
The scientific project or experiment that acquired the data
Data that were acquired to support a project/experiment (e.g. - GATE) or that can be used as ingest for a project (e.g. - WRF)
The structure of the bitstream used to encapsulate the data values in a record or file (e.g - ASCII, netCDF, etc.)
The name of the location or region for which the data are valid
  GRIB Library

GRidded In Binary is a WMO standard for the efficient exchange of gridded binary data. We maintain a library of routines for converting grids into and out of the GRIB format. These are general-purpose routines, available for many different computing platforms. If you have GRIB data from a DSS dataset, you should look in that dataset first for an access program. We also maintain online documentation for GRIB.

The Research Data Archive is managed by the Data Support Section of the Computational and Information Systems Laboratory at the National Center for Atmospheric Research in Boulder, Colorado. NCAR is sponsored by the National Science Foundation.
