how to get the values from netcdf to ascii format through matlab?
显示 更早的评论
The data is in .nc form (e.g data.nc). 1) How to extract a grid from this file format? 2) How to find the values of the extracted grid in ascii form?

Girija, please say more. Its hard to give a helpful answer since your question does not have enough information. For example - how is the data in the netcdf file structured? Do you have lat /lon and data. Are they 1D 2D or nD? What do you mean by ASCII form? As a variable as a CSV file a text file?
To get started, please have a look at the ncread function.

Check out the names of the variables with ncdisp('data.nc') and if one of the variables is lat, you can load it with
lat = ncread('data.nc','lat');
Then you can write variables to ascii with dlmwrite.

It is difficult to understand your question. Try to ask a specific question about a specific step that you're having trouble with.

Take a look at the function ncread. Here you can specify the indices of the starting location of a variable and the number of elements to be read. If a variavle "var" is a two dimensional variable, then you can use the following line of code:
ncread('data.nc','var',[1, 1], [1,1])
