Hi,
I'm new to the group and I already have a question.
I'm trying to run an interpolation between one array of model-generated
latitude/longitude grid points and a second array of gridded ozone values
(with lon being along the x and lat being along the y). What I need to do is
take the array of grid points of unknown ozone values and interpolate the
known ozone values to the unknown ozone grid points. How do I let IDL know
the latitude/longitude coordinates of the known ozone values, so when I go
and interpolate those ozone values to the unknown ozone value grid points it
knows where to look on the data array? The array of known ozone values
ranges from a fixed interval of both lat and lons and is 77 (lons) x 34
(lats). I need to have at least 5 places to the right of the decimal since
the desired interpolated grid points are model points and will be input with
that number to the right. I know this sounds confusing, but it sounds like
something IDL should be able to do pretty easily. Let me know if you need
any further information and thanks.
Cheers,
Jack Creilson
