Data with erroneous geolocation information are being reprocessed to eliminate data that do not meet specifications. Reprocessing of all affected data is expected to be complete in Spring of 2009. For information regarding the dates and times of the maneuvers with the affected data, visit the MODIS Land Quality Assessment Web site at http://landweb.nascom.nasa.gov/cgi-bin/QA_WWW/newPage.cgi?fileName=Maneuvers. http://nsidc.org/data/news.html#13nov08_nsidc0027 http://nsidc.org/data/news.html#13nov08_nsidc0027 Thu, 13 Nov 2008 13:55:00 MST NSIDC has recently updated the Northern Hemisphere TOVS Pathfinder Path-P Daily Arctic Gridded Atmospheric Parameters data set.
