Fundamental CDRs

Fundamental CDRs are composed of sensor data (e.g. calibrated radiances, brightness temperatures) that have been improved and quality controlled over time, together with ancillary calibration data.

NOAA CDRs are derived from a variety of satellites and instruments. The launch, maintenance and decommissioning of satellites can be found on the WMO's Observing Systems Capability Analysis and Review Tool (OSCAR) website.  

NOAA Satellites 

As satellites or instruments change, there will be changes to how CDR data is derived and provided. Information on the impact of each individual CDR will be updated as resources allow. The Fundamental NOAA CDRs are also available via Amazon Web Services (AWS).
