 FindL1Bmet finds specific MODIS Level-1 granules that have been previously created
  by the DAAC. The user enters in the latitude and longitute they wish to find, 
  and the dates in  which they wish to find the data. FindL1Bmet then searches 
  through windhoek's archive of L1B meta data for granule matches. 
 The code assumes that the DAAC has been pushing L1B.meta data files to windhoek, 
  in the form of MOD021KM*.hdf.met, located on windhoek in the directory, 
  ///

 Caveats:  
		1) This program works only for identifying daytime granules
	        2) This program cannot deal with the international date line
		3) This program cannot identify regions over the poles

 Compilers needed:
		1) Fortran 90


 Files:
		FindL1Bmet.readme.: 	   This file 
		FindL1Bmet_V1Coord.check:  Latitude/Longitude you wish to find
	        FindL1Bmet_V1Coord.f90:	   Fortran code for matching L1Bmet data location
		FindL1Bmet.sh:		   Shell script to run code
		

 How to run:
		1) use chmod +x to make FindL1Bmet.sh exectutable
		2) edit FindL1Bmet.sh as needed
			A) Directory where you want this code
			B) directory located L1Bmeta data
				/ingest/L1Bmet  on windhoek
		 	C) date(s) to look for, 
			   it is currently set to look for up to 70 days previous to today's date.
				
		3) Compile FindL1Bmet_V1Coord.f90:	  compile using
				f90 -o FindL1Bmet_V1Coord FindL1Bmet_V1Coord.90
				(no extensions needed)

		4) Edit FindL1Bmet_V1Coord.check for location

 Created by Rob Levy: SSAI/NASA-GSFC Code 913, sometime during 2000. 

 Note that this code is intended to run on windhoek, and is not guaranteed.
