  "description": "The NCEP Climate Forecast System version 2, the operational coupled atmosphere-ocean-land forecast, ensemble member 01, six-hourly from 6 to 6552 hours — thirty-nine weeks of a nine-month run. The surface fields are on the model's native T126 Gaussian grid (0.9375°) and the sea level pressure, pressure-level heights, temperatures, winds, vertical velocity and derived water vapour flux on the regular 1° grid NCEP publishes them on, so each bundle states the grid its own planes are on. Two cycles a day (00Z and 12Z); only the newest is kept. The precipitation rate, downward shortwave radiation and total cloud cover are means over the six hours ending at each frame.",
