NCEP 29km eta model Surface Flux

Projects:

Summary

This dataset is the NCEP 29km eta model Surface Flux analyses and 3-hourly forecasts (out to 33 hours) collected during the VORTEX-95 project. The data are in GRIB format on a skewed lat-lon grid and on sigma surfaces. This is a high volume dataset: one run of surface flux is about 60 Megabytes(MB)! This output includes pressure, geopotential height, temperature, precipitation, specific humidity, soil temperature and moiture content, u and v wind components among many other parameters including many flux parameters. NOTE: At the time of VORTEX-95, the 29km eta model was being run in experimental mode, so use the model output with caution.
