***************************************************************** Journal for accession number: 0281356 Created on: 2023-08-06 12:30:12 UTC By: National Centers for Environmental Information Source: These data were submitted for archive to NCEI from the Center for Satellite Applications and Research (STAR), NOAA, as part of the oceanographic products from SAR-wind. Actions: Data were uploaded by STAR to the Production Distribution and Access (PDA) system; NCEI downloaded the data and SHA-384 fixity information files from the PDA. The data files were validated against the SHA-384 fixity information. An archival information package (NCEI Accession) was generated and the netCDF and GeoTIFF files were copied to the data/0-data/ directory. A sample browse graphic for the Sea Surface wind data provided by the producer was copied to the about/ directory. Files: about/ This directory contains files created by NCEI staff, including 'negotiable' information between NCEI staff and the data provider. 0281356_preview.png - Sample of a regional map for Level-2 Sea Surface Wind from SENTINEL-1A data. data/0-data/ This directory contains the data files as submitted to NCEI, including both graphics and NetCDF data files. 1.

Times prior to 2000 will have a leading minus (-) sign. DDD.DD[EW] = is the Longitude in decimal degrees + (East or West) DD.DD[NS] = is the Latitude in decimal degrees + (North or South) PP = is the transmit and receive polarization (HH, VV, HV, VH) F# = Geophysical model function ID used for the conversion where F (a single digit) is frequency and # is a positive number (1 or more digits), which represents which geophysical model function (GMF) was used for the wind retrieval. The default value is 0. Model = is a string designating the model winds used for direction ("Fixed" if no model directions were used) wind = Data type level2 = Level-2 derived product .nc = netCDF file extension for example: S1A_ESA_2015_10_06_00_20_29_0497406029_35.47W_76.28S_HH_C5_GFS05CDF_wind_level2.nc 3. New GeoTIFF files (processed in NCCF): SAR-Wind---___sYYYYMMDDHHMMSSS_eYYYYMMDDHHMMSSS_cYYYYMMDDHHMMSSS.tif Where: SAR = Satellite instrument Wind = Parameter short name Polarization = The transmit and receive polarization (HH, VV) Lat = two digit latitude values + N or S (North or South, respectively) Lon = three digit longitude values + E or W (East or West, respectively) Version = vMrN, current is v1r0 Satellite_ID = s1a (Sentinel-1A) StartDateTime = beginning observation date/time: "YYYY" = 4-digit year "mm" = 2-digit month (01-12) "dd" = 2-digit day of month (01-31) "hh" = hour (00-23), "nn" = minute (00-59), "sss" = second (00-59, plus the nearest tenth second). EndDateTime = ending observation date/time: CreateDateTime = data file creation date/time: tif = TIFF format for example: SAR-Wind-VV-70N-159W_v1r0_s1a_s202206281716270_e202206281716560_c202206282157449.tif 4.
