This is data of a new re-analysis of the AVHRR data archive, developed within the "AVHRR Pathfinder Version 5 SST Project (Pathfinder V5)" at Rosenstiel School of Marine and Atmospheric Science (RSMAS), University of Miami, Fl, NOAA National Oceanographic Data Center (NODC), and NASA Physical Oceanography Distributed Active Archive Center (PO.DAAC). A new version of the Pathfinder Algorithm is used, that allows, among others, the retrieval of twice-daily global SST maps. Important improvements are the more accurate landmask, a finer spatial resolution (4 km instead of 9 km) and the inclusion of sea ice information. Additionally, data quality flags have been improved, e.g. with regard to the aerosol influence.
This is version 5.2! The official name of this data set is "AVHRR Pathfinder Version 5.2 L3-Collated (L3C) sea surface temperature".
Important: For cloudy areas no SST values can be retrieved; here particularly the data set with daily resolution contains numerous gaps. Still it is the daily data we are offering here - separately for day and night overpasses. Monthly average SST data will be generated and provided later.
