I want to investigate atmospheric refraction and i am using Aqua/ Airs satellite data. These are atmospheric parameters
(1) Air temperature
(2) Geopotential height
(3) Relative Humidity
All these parameters are at different pressure levels (1000, 925,800,....1 hpa). It is Aqua/AIRS version 6 level 3 product. Please suggest me which interpolation technique will be best suited for this data sets? This data set is in text format.
I have these softwares : ArcGIS 9.3, Erdas,Envi, Matlab etc suggest also other software which can also assist me in text file data.
