We are using jupyter notebook developed by Liz Hearn to calculate CTM values at points defined for the GFM.
Contents
GFM Points
AP has created a discretized version of the GFM. The coverage region for the GFM is similar to the CVM-H GTL coverage region. Corner points from the GFM grid are listed below.
The resolution of the GFM 3D voxel data set is 10km x 10km x 1km (depth).
Each level of the GFM has 8256 points, and the depth goes from -100km to +4km (8256 x 105 = 866880) points.
Corner Points from GFM file:
- -122.681200, 29.709900 -123.205500, 37.335600 -112.481200, 37.412300 -112.864200, 29.767300
A white-space delimited file that defines the GFM region types for each of these points is posted here. This is the updated file that include elevation for each point.
- GFM Cell Points and Data (Warning 13MB zip file download. 65Mb expanded as text file)
The cell location in this file use the CVM-H convention of elevation relative to sea level in meter, with positive values above sea level, and negative values depth below sea level. The cells extend from -100km to 4km.
Example GFM Data Format
This shows the format of the GFM cell data, before it is updated with CTM heatRegionID and CTM temps. The elevation data is from the GFM topography surface. The last 9 lines are CTM test points, with known results, used to verify that the script used to populate the heatRegionID and Temp are producing the correct results for the GFM points.
