Hydrological Properties CDR

Configuration Item ID: 01B-38c

The Hydrological Properties Climate Data Record (CDR) integrates hydrological variables collected by the NOAA Advanced Microwave Sounding Units A and B (AMSU-A/B) and Microwave Humidity Sounder (MHS) into a long-term record that spans from 1998–present. It contains roughly a 48km (AMSU-A) and 16km (AMSU-B/MHS) resolution over the entire globe with 30 MHS and 90 AMSU-B/MHS observations per scan. This CDR is useful for water cycle applications, identifying climate extremes and validating other observations.

Covers parameters such as total precipitable water (TPW), cloud liquid water (CLW), sea-ice concentration (SIC), land surface temperature (LST), land surface emissivity (LSE) for 23, 31, 50 GHz.



Covers parameters such as ice water path (IWP), rain rate (RR), snow cover (SC) and snow water equivalent (SWE). To improve accuracy, visual inspections and verification of the various corrections are applied. The MHS sensor replaced AMSU-B on NOAA-15, 16, and 17 satellites.
