Low Earth Orbit/Geostationary Orbit (LEOGEO) Atmospheric Motion Vectors (AMV) text output data

These are derived from specialize satellite composite imagery using both low Earth orbiting (LEO) and geostationary (GEO) satellites, since the product is known as LEOGEO AMVs. Files are labeled as: WIND.xx.Dyyddd.Thhmm00.txt where xx is the polar region, SP for South Pole region and NP for North Pole region, yy is the last two digits of the year, ddd is the day of the year, hh is the hour, and mm is the minutes.

The columns of data inside the files have: type = IR is the infrared satellite composite used to make the AMVs sat = LG is for LEOGEO type of wind day = Day, in yyymmdd format, with yyyy the year, mm the month, and dd the day hms = Time in Hours, Minutes and Seconds, UTC lat = Latitude (positive North) lon = Longitude (positive West – not East longitudes are negative) pre = Pressure level of the wind in millibars spd = Wind Speed in meters per second dir = Wind direction rff =Recurve filter Flag (see Hayden and Purser 1995, Velden et al. 1997) qi = Quality Indicator (see Holmlund, 1998 and Holmlund et al., 2001) Hayden, C. and R.J. Pursor, 1995.
