Hydrological Properties

Sample output image derived from Hydrological Properties, representing a composite of total precipitable water, surface temperature, rain, sea ice, and snow overlaid on a projected globe map.

This dataset provides scientific researchers a high quality Climate Data Record (CDR) of Hydrological Properties.

Instrumentation utilized is the NOAA Advanced Microwave Sounding Unit-A (AMSU-A), Unit-B (AMSU-B) and Microwave Humidity Sounder (MHS) to create a Thematic Climate Data Record (TCDR) for "window channels." The data period of record begins in 1998 with monthly updates. It contains roughly a 48 km (AMSU-A) and 16km (AMSU-B/MHS) resolution over the entire globe with 30 MHS and 90 AMSU-B/MHS observations per scan. The AMSU-A portion of the Hydrological TCDR 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. The AMSU-B/MHS portion of the Hydrological TCDR 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 Hydrological TCDR is useful for water cycle applications, identifying climate extremes and validating other observations.
