Somewhere throughout the URS Authentication the parameters sent with a url are being downshifted (lowercase). The, now lowercase, parameters are causing errors when trying to receive data from urls where the variables are represented by an Uppercase letter.
For example: running getdap https://airsl2.gesdisc.eosdis.nasa.gov:443/opendap/Aqua_AIRS_Level2/AIRH2CCF.006/2002/242/AIRS.2002.08.30.225.L2.CC_H.v184.108.40.206.G14101125857.hdf.dods?Latitude
results in: Error while reading the URL: https://airsl2.gesdisc.eosdis.nasa.gov/opendap/aqua_airs_level2/airh2ccf.006/2002/242/airs.2002.08.30.225.l2.cc_h.v220.127.116.11.g14101125857.hdf.dods?latitude.
Note that “Latitude” has been downshifted to “latitude” and therefore getdap was unable to locate the variable.
We need to get in contact with the guys in charge of the Authentication process and see what is going on with the url when it is being passed around.
