Re: Level 1&2 browser - scenes not available for ordering

Hi Sean. Thanks for your reply.
I tried download the L1 data and process locally, however the L1&2 browser does not find all images in that area. By the way, I already solved my problem performing a search on L2 reprocessing data set.

Thanks.
Fabio.

Level 1&2 browser - scenes not available for ordering

This issue is fixed. However there is another problem, specially with searching on SeaWiFS MLAC data. Steps to reach the problem (this problem occurred also before to solve the ORDER DATA problem): 1) In L1&L2 browser set (check box) only SeaWiFS (MLAC) 2) then select any year between 1997 and 2...

Cropp and reproject problems with output format

I use only Linux.

OK.
But why if I consider netCDF-CF format I'm able to crop than to reproject? I'm trying to do it from  this way because I'm working with the full mission of data(2002-present). So, if I can crop and than reproject I will not spend to much time.
