  1. 1-st Request: u, v, relative humidity, temperature, and geopotential height at 1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 10mb. These should be available at a 6-hour frequency (0Z, 6Z, 12Z, 18Z). We also need the SST, surface pressure, snow water equivalentand soil temperature, wetness and liquid fraction 2-nd request:2-m air t, 2-m specific or relative humidity, 10-m wind components, Mean sea-level pressure, Geopotential height of the surface or elevation, Land mask and geopotential heights of pressure surfaces that are beneath the local land/ocean surface DATA FILES AVAILABLE FOR TESTING horz_maps_2d_21x21_01_2008 horz_maps_sigma_21x21_01_2008 horz_maps_pressure_21x21_01_2008 LandFractionAndElev_21x21 IDL ROUTINE TO READ THE DATA read_horz_maps_21x21fcst.pro
