Thank you mister!

Hello.I've downloaded from NASA Ocean Color .L1A files of December 2020, with the following limits of area: -16.3, -23.3, -43, -37.5But when I ran the script seeking to generate GEO, L1B, L2 and L3 files, I'm geting the following errors:Percent valid data (0.00) is less than threshold (95.00...

Your Band Math expression worked perfectly for what I needed.
About using the ArcGIS, I'm really more used to work with geoTIFF files on that, but considering those advantages on NetCDF4-CF I'll check it out.

Thank you for your help sir. Have a very nice day!

The math band generates the new raster and I'm checking it on the own Seadas. I'm not exporting or saving the raster. I acctually do want to export it as Geottif to work on arcgis; but since the NaN isn't being replaced by a number there's no reason for me to export the raster image....

I did use the (nan) function, but the NaN values weren't replaced and the values different of NaN became 0....so the NaN didn't become a number...
Any ideia why does this happens? I'm really stuck at this...

Hi all!I've got some .L3m turbidity maps which has some NaN values. I need to replace every NaN value by the number -9999.Can someone help on how can I do it, through Math Band, for example?Thank's for any help!Beiral.

Hi,I'd like to know if there's a way to crop multiple .L3m images, already processed, setting latitude and longitude limits, through linux command lines or some kind of shell script...how can I get started with these commands or scripts to make the cropping non manual...I'm really stuck ...

Thank you very much for your help Sean...Regards!

Hi all!
The product of MODIS equivalent to water leaving reflectance is rhos? Or do I need to calculate Rrs*Pi?
Thanks for any help!!

Hi Sean, sorry to bother you, but I still got some doubts....I've processed a whole database of many years using my script and ms12_filter.dat as I sent here, and It just worked perfectly to all files.Do you got any ideia why it happens only with this file?And what is exactly this filter kernel?...
