NCEP 29km eta model 3-D Grids

Projects:

Summary

This dataset is the NCEP 29km eta model gridded 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 VERY high volume dataset: one run is about 400 Megabytes(MB)! This output includes pressure, geopotential height, temperature, u and v wind components, vertical velocity, specific humidity, precipitation, among others. NOTE: At the time of VORTEX-95, the 29km eta model was being run in experimental mode, so use the model output with caution.
