hello every one,
I have INSAT3D SST satellite data. I am able to read the latitude, longitude and sst variables but i am unable to process it.
here is the mat-lab code.
figure
s1 = h5read('F:\3DIMG_01OCT2013_0000_L2B_SST.h5','/SST');
l1 = h5read('F:\3DIMG_01OCT2013_0000_L2B_SST.h5','/GeoX');
l2 = h5read('F:\3DIMG_01OCT2013_0000_L2B_SST.h5','/GeoY');
set(gcf,'units','normalized','outerposition',[0 0 1 1]);
m_proj('Mercator','long',[20 140],'lat',[0 90]);
m_coast('patch',[.8 .7 .6],'edgecolor','none');
m_grid('tickdir','out','yaxislocation','left',...
'xaxislocation','top','xlabeldir','end','ticklen',.02);
hold on;
m_pcolor(l2,l1,s1');
shading interp;
