As a result, individual measurements are arranged in curved \u201cscans\u201d on the Earth. Each measurement footprint is generally elliptical, with a range of alignments relative to fixed directions on the Earth. Taken together, these geometrical features present a challenge for users who want collocate microwave radiances with other sources of information. These sources include maps of surface conditions (often available on a regular latitude\u2013longitude grid), information from other satellites (which will have a different, non-aligned scan geometry), or point-like in situ information. Such collocations are important for algorithm development and validation activities. Some of these challenges associated with collocating microwave radiances would be eliminated by resampling satellite data onto circular footprints on an Earth-fixed grid. This is because circular footprints help enable accurate collocations between satellite sensors on different platforms whose native footprints are usually ellipses canted at varying angles. Here, we describe a computationally efficient method to accurately resample microwave radiances onto circular footprints, facilitating comparisons and combinations between different types of geophysical information.<\/jats:p>","DOI":"10.3390\/rs15205047","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T11:53:56Z","timestamp":1697802836000},"page":"5047","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Computationally Efficient Approach for Resampling Microwave Radiances from Conical Scanners to a Regular Earth Grid"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6020-9354","authenticated-orcid":false,"given":"Carl","family":"Mears","sequence":"first","affiliation":[{"name":"Remote Sensing Systems, 444 Tenth Street, Santa Rosa, CA 95401, USA"}]},{"given":"Andrew","family":"Manaster","sequence":"additional","affiliation":[{"name":"Remote Sensing Systems, 444 Tenth Street, Santa Rosa, CA 95401, USA"}]},{"given":"Frank","family":"Wentz","sequence":"additional","affiliation":[{"name":"Remote Sensing Systems, 444 Tenth Street, Santa Rosa, CA 95401, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,20]]},"reference":[{"key":"ref_1","unstructured":"Ulaby, F.T.
