RAINEX: NOAA N42 P-3 Stepped Frequency Microwave Radiometer (SFMR) Data

Summary

This dataset contains Stepped Frequency Microwave Radiometer (SFMR) data from the NOAA N42 aircraft collected as part of the Hurricane Rainband and Intensity Change Experiment (RAINEX). It includes data collected during hurricanes Dennis, Ophelia, Rita, and Wilma. These data are in NetCDF format.

Additional information

Identifier	DOI: https://doi.org/10.26023/4W6Z-253J-2709
Data Quality	final
Versions	1.0 (2007-11-05) 2.0 (2017-10-26): This version includes SFMR data reprocessed using the new operational algorithm that is based on Klotz and Uhlhorn (2014). The updated algorithm improves the separation of the wind and rain in the microwave signal in order to reduce a high wind speed bias at wind speeds below about 60 kt. In so doing, rain rates are also more representative within the instrument limitations. A low bias in the strong wind speeds (over 120 kt) is reduced as well. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
