I am using L2 input data to create L3 space and time binned products but cannot get the different satellite data into the L3bin or SMI tools together.
My goal is to merge both the Aqua & Terra products into one Seadas SMI file. Can i do this using any of the L2 / L3 or SMI generation tools?
There is no reason why you shouldn't be able to toss Terra and Aqua L2
files at the L3 code to merge the two. First, create sensor specific
L3 files using l2bin. Then give l3bin the resulting sensor specific bin files.
You must make sure that the products are the same, though. For example,
you cannot bin MODIS nLw_551 with SeaWiFS nLw_555, you can bin MODIS
chlor_a with SeaWiFS chlor_a (chlor_a = chlor_a, 555 != 551). This should
not be a problem for Aqua/Terra merger though.
I expected as much, however when i try to input Terra and Aqua files to l3bin i get the following error.
"The file 'terra_file' is not the same type as 'aqua_file' please remove this entry and try again.
Is there anything special i should be doing in the l2bin stage?
May i qualify this statement. I only receive the error message from the gui...The command line works fine.
Thanks for the help Sean.
Yep. The GUI code checks to make sure that the same sensor is used for the input files. I'm sure we probably did that originally as a sanity check to keep users from binning seawifs and modis data together. Hopefully we can get out a quick fix for this tomorrow for you. Until then, bypass the GUI.
Go to our ftp site at samoa.gsfc.nasa.gov and change directory to seadas/pub/camallen. If you are using your own installation of IDL, get l3bin_filesel.pro and place it in your $SEADAS/idl_lib and $SEADAS/src/idl_procs/l3bin directories. If you are using the embedded IDL, get seadas_idl_lib.sav and place it in your $SEADAS/idl_rt directory. Try again and let me know if it doesn't work for you.
Thanks Mark - It works fine in the GUI now.
