Trying to open L3 files without sucsess

SeaDAS can not open L3 bin files, but can view L3 mapped files.  The command line program "l3mapgen" is used to convert a bin file into a mapped file.  Unfortunately, the command line programs only work on linux or a mac. We also have SMI (Standard Mapped Image) files on the webs...

Yes, there is an indexing bug in this product that slipped through.  It is already fixed and will be released when the new processing code goes out. Thanks for the pointing this one out.

Question: The full name of OC2M-HI algorithm

The full name of OC2M-HI algorithm

Here is the documentation for the OC2M-HI chlorophyll algorithm.  The "HI" just means the algorithm is using the MODIS high resolution bands.

l2gen will produce this product if you ask for "chl_oc2" using a MODIS file as input.

L3mapgen interpolations

When you use "interp=area" you can also set the "fudge" parameter to make each pixel bigger.  This will average the neighboring pixels, but will obviously decrease your resolution.Are you sure the artifact is introduced by l3mapgen and not l2bin?Can you put the bin file and ...

L2 Bin - processing ocean color data

Could you post what is in the par file.  The problem is that 0 pixels were binned.

Yes, it looks like the help file for l2bin does not list the return codes.  Here they are:

  return value: 0=OK, 1=error, 110=north,south,east,west does not intersect

Question: Installing SeaDAS with sudo or not?

Installing SeaDAS with sudo or not?

It is better to install SeaDAS as a normal user in your home directory or a dir that you have write privileges for.  I usually install it in

/home/<user>/local/seadas7.3.2

There will be issues with permissions if you install as root.
