\"MODIS<\/a><\/p>\n

Comparisons of the 1-km resolution MODIS fog\/stratus product with the 4-km resolution GOES fog\/stratus product help to underscore the improved ability to detect subtle features using higher spatial resolution satellite data. AWIPS images of the MODIS and GOES-11 fog\/stratus products (plus topography) covering the Monterey and Fresno, California regions on 19 May 2008<\/strong><\/a> (above)<\/strong><\/em> showed a patch of fog over Monterey (KMRY), Watsonville (KWVI), and Salinas (KSNS), with a narrow finger of fog that extended southeastward into the Salinas River Valley.<\/p>\n

Farther inland over central California, the MODIS fog\/stratus product imagery revealed a noisy “false fog\/stratus signal” over parts of the San Joaquin Valley, due to the high emissivity of desert soils that covered the non-agricultural portions of the valley (the contrasting patchwork of green agricultural fields versus brown to gray non-agricultural areas was very evident on 250-m resolution MODIS true color imagery<\/strong><\/a> from the previous day)<\/em> — regions with a lower MODIS Normalized Difference Vegetation Index (NDVI) generally corresponded with regions that exhibited a more pronounced “false fog\/stratus signal” (below)<\/strong><\/em>.<\/p>\n

\"MODIS<\/a><\/p>\n

Images centered off the coast of Southern California and Baja California on 20 May 2008<\/strong><\/a> (below)<\/strong><\/em> revealed several ship tracks in the marine stratocumulus cloud deck that was offshore. Once again, such small-scale features showed up with greater clarity on the MODIS fog\/stratus product imagery. These comparisons give a bit of a preview of the types of improved products that will be available using the Advanced Baseline Imager (ABI)<\/strong><\/a> instrument on the upcoming GOES-R<\/strong><\/a> satellite (scheduled to be launched in 2014),<\/em> which will offer IR imagery and products at a 2-km spatial resolution (at 5-minute intervals on a routine basis)<\/em>.<\/p>\n
