Computing 2D curtains with CDO
Added by Angela Meyer over 10 years ago
Hi,
I'd like to plot a curtain (= altitude on y-axis and orbit track on x-axis) through ERA-Interim data. By 'orbit track' I mean a straight line along the Earth's surface, whereby that line is generally not parallel to a latitude or longitude grid line - i.e. both lat and lon change along the track.
Is there a CDO command or script which generates such a 2D 'curtain', when provided with appropriate 3D gridded data and a list of lat/lon coordinates for the orbit track?
Cheers
Angela

Does anyone have a solution? I also would like to do along-track interpolation. Currently I do single-point interpolation for each point along a track individually using "cdo remapbil".

Define a curvilinear grid with one "curve". Here is an example with 10 points:
gridtype = curvilinear gridsize = 10 xsize = 10 ysize = 1 xvals = -150 -140 -130 -120 -110 -100 -90 -80 -70 -60 yvals = -70 -65 -60 -55 -50 -45 -40 -35 -30 -25
