How to calculate the transmittance according to the aerosol Luts(dtran_a,dtran_b...)

As the title, I have using the wavelength and view geometry to get the dtran_a and dtran_b, but I don't know how using these data to generate the transmittance. Are there some equations or scripts?

Regards,

Can't access the website of data processing components by distributed separately

Dear everyone,I remembered the processing component for OLCI (SEN-3A) was separately released as a test version, now I want to use it to process some OCLI data in terminal window. However, I can not access the website of data processing components now(http://oceandata.sci.gsfc.nasa.gov/ocssw/). Was ...

The result of Mosaic is too small generated by gpt.sh

Thanks George, the problem has been solved according to your recommendation. I had thought the pixel resolution was determined automatically like the reprojection tool, but that was wrong. I must assign a fixed value to execute mosaic oration, if not, the default pixel resolution 0.05 would be adopt...

The result of Mosaic is too small generated by gpt.sh

Hi Aynur,The problem has been fixed according to George's recommendation. I thought the pixel resolution was determined automatically according to different sensors(250m,300m,30m etc.) like the reproject operation. Now the mosaic works well. A file including the input file name and parameters fo...

Dear Aynur,
The input file size is ~48M, which exceeds sever nasa.gov(xx.xxx.xx.xx) limit, the mail was rejected by server.
And, how can I send the input file to you ?

Thanks Aynur. The result generated by mosaic tool though GUI is OK. Actually, this problem is common for those data after 2006, yet the results for those data in 2002-2005 are OK, I don't know why.Due to the input file size is large, I will send the data to your e-mail box (aynur.abdurazik@nasa....

The result of Mosaic is too small generated by gpt.sh

Currently, I try to process some MERIS data during 2002-2012 by the SeaDAS 7.3. The L2_FRS_OC product generated by l2gen is ok , but when I used the gpt.sh to make mosaic with reprojection and subset, the result is very weird. The width and height of mapped data is just 20*15 for a 2000km2 region(30...
