GRACE Matlab Toolbox (GRAMAT)


Updated 26 Apr 2018

View License on GitHub

GRACE Matlab Toolbox (GRAMAT) contains a set of open-source functions to process GRACE level-2 spherical harmonic coefficient products. Data processing functions in the GMT contain: (1) destriping of SH coefficients to remove “north-to-south” stripes and Gaussian smoothing, (2) spherical harmonic analysis and synthesis, (3) analyzing and reducing leakage effect in GRACE-derived mass variations, (4) analyzing regional mass variations in spatial and temporal domains. Matlab GUIs are presented to facilitate the use of functions in the GRAMAT.

您好,非常感谢您制作的工具箱。我初学MATLAB和GRACE,可能不太了解,在运行工具箱时出现了“degree C20 file does not exist!”,请问缺少的dir_c20是什么文件啊?

Ok, thanks.

Something wrong with the code? When I run the preprocessing, I found that some wrong information as follows:
"Error using fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in GRACE_Matlab_Toolbox_preprocessing_core (line 6)
num_file = fscanf(fid,'%d',1);

Error in GRACE_Matlab_Toolbox_preprocessing>PushbuttonCalculate_Callback (line 88)

Error in gui_mainfcn (line 96)

Error in GRACE_Matlab_Toolbox_preprocessing (line 42)
gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)GRACE_Matlab_Toolbox_preprocessing('PushbuttonCalculate_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback"
Could you help me to deal with this?

Let me try first, Great Thanks for your tool!


Change the acronym from "GMT" to "GRAMAT".
