Typically we talk about solar zenith and azimuth angles and satellite/platform angles. These are angles from the observed location to the sun or to the platform. So we can't use simple "zenith_angle" etc. view_angle and scan_angle could be used without the qualifier. That's a good suggestion. -- Evan _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
