STAR / SMCD / OPDB (Polar Products)

Purpose

This project provides research and development for the Advanced TOVS (ATOVS) system which derives Temperature and Moisture sounding products and Cloud and Radiation products, such as Cloud Top Temperature and Outgoing Longwave Radiation. Product images of the latest 24 hours can be viewed.

ATOVS Soundings

The ATOVS series of NOAA weather satellites has three "atmospheric" sounders, the High- Resolution Infrared Sounder (HIRS), the Advanced Microwave Sounder Unit (AMSU) and the Microwave Humidity Sounder (MHS). These sensors are used to derive operational Advanced TOVS (ATOVS) global sounding products for Temperature and Moisture.

Currently, the ATOVS is generating products from the NOAA-19 and MetOp-2 polar orbiting satellites. ATOVS derives global Temperature and Water Vapor profiles at 42 atmospheric pressure levels (1025 to 0.1 mb) levels.

ATOVS Cloud and Radiation products

The ATOVS system has been enhanced with new product algorithms for generating Cloud and Radiation type parameter suites. Like the sounding products, the Cloud and Radiation products are global, for both METOP-A and NOAA-19 and generated routinely in near-real time.

Example products are Cloud Amount, Clout Top Pressure/Temperature, Cloud Product Error, Outgoing Longwave Radiation and Layer Cooling Rate.
