2230549, experiment: SeaWinds on QuikSCAT Level 3 Daily Gridded Ocean Wind Vectors

data

Local copy of the Level 3 Ocean Wind Vectors of SeaWinds on QuikSCAT Data Set (daily mean measurements) downloaded via FTP from: ftp://podaac.jpl.nasa.gov/pub//ocean_wind/quikscat/L3/data/. Files are located under WELLE.ZMAW.DE: /scratch/local3/u290022/DATA/SATELLITE/Ocean_Wind/quickscat/L3/data. The SeaWinds on QuikSCAT Level 3 data set consists of gridded values of scalar wind speed, meridional and zonal components of wind velocity, wind speed squared and time given in fraction of a day. Rain probability determined using the Multidimensional Histogram (MUDH) Rain Flagging technique is also included as an indicator of wind values that may have degraded accuracy due to the presence of rain. Data are currently available in NetCDF converted from the original Hierarchical Data Format (HDF converted to NetCDF for CliSAP) and exist from 19 July 1999 to present. The Level 3 data were obtained from the Direction Interval Retrieval with Threshold Nudging (DIRTH) wind vector solutions contained in the QuikSCAT Level 2B data and are provided on an approximately 0.25 deg x 0.25 deg global grid. Separate maps are provided for both the ascending pass (6AM LST equator crossing) and descending pass (6PM LST equator crossing). By maintaining the data at nearly the original Level 2B sampling resolution and separating the ascending and descending passes, very little overlap occurs in one day. However, when overlap between subsequent swaths does occur, the values are over-written, not averaged. Therefore, a SeaWinds on QuikSCAT Level 3 file contains only the latest measurement for each day. This product is also referred to as JPL PO.DAAC product 109.
