RAMS model simulation output for "Cold Pool - Land Surface Interactions in a Dry Continental Environment"

Abstract

The RAMS output data is contained in three separate folders representing different simulations or simulation time periods as described in the accompanying manuscript. Each folder contains: HDF5 files (*.h5) and corresponding header files (*head.txt). Both analysis files and lite files are provided. HDF5 analysis files are named a-A-YYYY-MM-DD-hhmmss-g1.h5 and contain every variable that is output by the model. Restart simulations can be performed from analysis files. HDF5 lite files are named a-L-YYYY-MM-DD-hhmmss-g1.h5. Lite files only contain a small subset of variables and cannot be used for restart simulations. Four surface files needed for restart simulations: o ndh-N-YYYY-MM-DD-hhmmss-g1.h5 containing NDVI information o sfch-S-g1.h5 containing land surface information for the LEAF land surface model o ssth-W-YYYY-MM-DD-hhmmss-g1.h5 containing sea surface temperature information o toph-S-g1.h5 containing topography information A RAMSIN file, the namelist text file used to define all settings to run the simulation. The sub-folders are the following: PreColdPool_12-14LT/: This folder contains the RAMS analysis and lite file output for the first two hours of the simulation in which the convective boundary layer is allowed to develop but no cold pool is introduced. The time period is from 12:00 to 14:00 local time, analysis files are every 30 min, and lite files are every 5 min. FB_14-16LT/: This folder contains the RAMS analysis and lite file output for the FB (surface FeedBacks included) simulation described in the manuscript. In brief, a cold pool is introduced and it evolves over an interactive land surface. The time period is from 14:00 to 16:00 local time, analysis files are every 15 min, and lite files are every 1 min. NOFB_14-16LT/: This folder contains the RAMS analysis and lite files for the NOFB (NO surface FeedBacks) simulation described in the manuscript. In brief, horizontally homogeneous but temporally variable surface sensible and latent heat fluxes are prescribed; these prescribed fluxes are determined from the average environmental fluxes in the FB simulation, as described in the manuscript. The time period and output frequency is the same as for the FB simulation.
