Hello, Let me explain the following calculations ... Lets consider (Rrs) for Modis/Aqua. Calculations follow https://oceancolor.gsfc.nasa.gov/atbd/chlor_a/#sec_2 (Algorithm Description) t1 = 0.25 t2 = 0.35 Reflectances: R1 = 0.006004000856137 (443) R2 = 0.004496000859945 (488) R3 = 0.003296000862974...

Hi. I was looking at the source codes of l2gen algorithm on page: https://oceancolor.gsfc.nasa.gov/docs/ocssw/get__chl_8c_source.html At this part of the code 252 float chl_oci(l2str *l2rec, float Rrs[]) { 253 static float t1 = 0.25; 254 static float t2 = 0.35; 255 256 float chl1 = chlbad; 257 float...

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.

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...

Hi, I'm getting 404 Not Found page when I click on orderdata. I did all suggestions on this post. But... Computer 1 - 404 Not found... $ firefox --version Mozilla Firefox 102.10.0esr $ uname -a Linux "computer1" 5.10.0-21-amd64 #1 SMP Debian 5.10.162-1 (2023-01-21) x86_64 GNU/Linux $ lsb_r...

Hi,Last version of Seadas (7.5.3) does not open using java openjdk11 or oracle 12. I'm using Debian Buster.Java 8 from oracle is no longer available to download publically.Using Java openjdk11 when I try to open Seadas by comand line I get this error and Seadas start to open but close sooncortiv...

Hi.I think I could not express myself in a right way.The problem is about the output format of the file: netCDF-CF and netCDF4-CF.If I ask to Seadas to save the output files (the cropped and reprojected files) as a netCDF-CF format (remember gpt.sh ......... -f netCDF-CF) I'm able to crop first ...

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.

Fabio.

Hi.The problem is with the netCDF4-CF.Source file: A2015042183000.L2_LAC_OC.ncIf I reproject the file first and than cropp (the reprojected file) there is no problem. These are the two command lines. reprojectgpt.sh reproject.xml -Ssource=A2015042183000.L2_LAC_OC.nc -t A2015042183000.L2_LAC_OC_repro...

Thank you Danny. Your last two posts were very helpful!
