Scatterometer and Radiometer Data Sets

The Scatterometer Climate Record Pathfinder currently archives selected image and data products from these scatterometer missions. First select a sensor below, then the study region. Alternately, you can first select the study region then the sensor. Most users will be interested in all-pass or local-time-of-day A-type .SIR images.

Scatterometer Instrument Comparison

* Note: By JPL convention the SeaWinds instrument flown on the QuikSCAT satellite is termed "QuikSCAT", while the SeaWinds instrument flown on ADEOS2/Midori2 is termed "SeaWinds". The third SeaWinds instrument was flown on the ISS 2015-2016 and was termed "RapidScat".

** Created from the recalibrated version 7 of the F13 SSM/I data record produced by Remote Sensing Systems (RSS) www.remss.com. A full set conventional and enhanced resolution images of all SSM/I and SSMIS sensors and channels is available as part of the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR (nsidc.org/data/nsidc-0630).

*** The National Snow and Ice Data Center (NSIDC) hosts a more comprehensive set of enhanced resolution radiometer brightness temperature products that were produced using SCP techniques for the Calibrated Passive Microwave Daily Equal-Area Scalable Earth (EASE) Grid~2.0 Brightness Temperature (CETB) Earth System Data Record (ESDR) project. These include all SSM/I, SMMR, SSMIS, and SMAP radiometer sensors and channels.

While not required, we ask you to please send us your email addresss (via email to long@ee.byu.edu) when using data from the Scatterometer Climate Record Pathfinder (SCP). Your email address enables us to (1) keep you informed of any updates to SCP data and/or software and (2) justify continued funding to support product generation and distribution. Your email address will not be used for any other purpose.

We would also appreciate a notice of the publication where the image or data is used or appears. Send to long@ee.byu.edu.
