Microwave Integrated Retrieval System (MIRS) - Objectives
The overarching objective of the Microwave Integrated Retrieval System (MIRS) is to contribute to the execution of the NOAA elements in the Integrated Earth Observation System (IEOS), which is a NOAA priority (Mission Support).
MIRS aims at providing timely and effective acquisition and delivery of satellite-derived information that supports requirements from the Mission goal. The integrated and generic natures of MIRS make it possible to reduce significantly the amount of time spent developing retrieval algorithms for new sensors, which in turn reduces dramatically the time needed to transition to operations.
Scientifically, the objectives of MIRS include:
- An improved temperature and moisture profiles retrieval,
- the extension of the retrieved products to non-standard surfaces including sea-ice and snow-covered land,
- the retrieval in all-weather conditions including cloudy and precipitating conditions and
- an improved set of retrieved surface properties whose derivation is based on the retrieved emissivities instead of directly from the brightness temperatures.
MIRS retrievals have also the objective to be useful for climate studies. Their independence from Numerical Weather Prediction (NWP) models outputs, including from the surface pressure, and the consistent treatment of all sensors using virtually the same retrieval algorithm, make the derived products indeed ideal to study the trends of several products. The MIRS web site has been designed to allow the user to monitor changes/changes in several products simultaneously and from different sensors.
