About mascon file #137

Open LuoLanhua opened 12 months ago

LuoLanhua commented 12 months ago

I would like to calculate the mass change of the mascon, but I am not very familiar with how to generate the necessary mascon file. I am also not entirely clear about the data input required in the mascon.py program. Would you mind helping me understand it better and provide an explanation?

What the mascon program is looking for is an index file (ascii) containing the paths to sets of individual harmonic files (which can be ascii, netCDF4 or HDF5). The harmonic files are (typically) created using a unit water thickness over a region of interest.

In previous work (e.g. Sutterley et al., 2020) we used spatially organized sets of spherical caps for our mascon kernels.

Thank you very much for your help. I will read this article carefully.
