DATA & CODE:

Millimeter-Wave Precipitation Code
The Millimeter-Wave Precipitation (MWP) code provides a method for estimating precipitation rate from passive microwave data obtained near 54 and 183 GHz. The code was written for the Advanced Microwave Sounding Unit (AMSU) aboard the NOAA-15, 16, and 17 satellites. It produces estimates of precipitation rate and precipitation-induced brightness temperature perturbations for some channels in the 54-GHz band at 15-km and 50-km resolutions. For discussion of the code and how to use it, please see below.

To potential users of the MIT AMSU precipitation rate algorithm (MWP):
We have recently assembled code to enable others to run our current precipitation-rate retrieval algorithm (the "Millimeter-Wave Precipitation [MWP] algorithm") on NOAA 15/16/17 AMSU-A/B data. This link provides a quick overview of the code's function as well as some additional information.

We would be happy to work with you as you bring the code on-line, and expect you will have no major problems. If you have technical questions, please contact Fred Chen. We you also appreciate hearing about your successes.

For advanced users:
The file precip_swath.c can be incorporated into another C program. This link shows how that can be done.

Global precipitation maps:
This poster has a few images showing global precipitation maps produced using data from all three NOAA satellites carrying AMSU.
