[las_users] How to create Virtual Variable



Hello,


I have two data files with the same spatial resolution and grid structure.


File 1: (Sea surface temperature)

OPENDAP: http://opendap.jpl.nasa.gov/opendap/OceanTemperature/avhrr/L3/pathfinder_v5/monthly/day/04km/2000/07/200007.s04m3pfv50-sst-16b.hdf.html

or 

FTP: ftp://podaac-ftp.jpl.nasa.gov/OceanTemperature/avhrr/L3/pathfinder_v5/monthly/day/04km/2000/07/200007.s04m3pfv50-sst-16b.hdf


File 2: (Quality Flag)

OPENDAP: http://opendap.jpl.nasa.gov/opendap/OceanTemperature/avhrr/L3/pathfinder_v5/monthly/day/04km/2000/07/200007.m04m3pfv50-qual.hdf.html

or 

FTP: ftp://podaac-ftp.jpl.nasa.gov/OceanTemperature/avhrr/L3/pathfinder_v5/monthly/day/04km/2000/07/200007.m04m3pfv50-qual.hdf

 


Is there a way in LAS to provide the data users option to extracting SST data from "SST variable" based on a the highest Quality Flag value  from the "Quality Flag variable" and creating a new Virtual Variable called "Best SST".



I've read the FAQ on "Serving Virtual Variables"  but it looks like this is for an older version of LAS server.  Is there a solution for doing this in LAS 7.3

Thanks,
