how to turn netcdf into contour map

14 views (last 30 days)
I have T2M data plot and want to put it into a contour plot at lat and lon 80.5N and -58W showing T2M over time how do I do this?
I've never used this before

Hi Abigail,
The first thing I do with a netcdf file is type
to see what's inside it. If you have some variables named latitude, longitude, and T2M, read them in like this:
lon = ncread('','longitude');
lat = ncread('','latitude');
T = ncread('','T2M');
Most of the time with NetCDF's of climate data, you'll have to swap the first two dimensions of any gridded data. That probably looks like this:
T = permute(T,[2 1]);
for 2D data or
T = permute(T,[2 1 3]);
if T is a 3D data cube.
Assuming T is 3D where the third dimension corresponds to time, you could contour the first time slice like this:
But you say you want to show T over time. What exactly do you mean by that?

Thank you
I managed to get it working but had to rewrite the code
