getting numeric chlorofil A color as CVS file
Posted: Thu Sep 02, 2021 4:50 pm America/New_York
Hi there,
You have big chlorophyl-a datasets obtainable from MODIS Terra and Aqua L3 (global view) for almost a 20-year period. But the spatial resolution of them is too coarse to study (4 km).
you present it as an NC file (pixelmap). When I open it with SEADAS I am facing a pixelation problem (pls see attachment).
(Note: I know at the moment, via Hawkeye sat., it's possible to obtain OC maps with significantly higher resolution but the problem is about the lack of dataset dating 2020 before.)
How can I get numeric chl-A data [as lat, long, chl-A (mg/L)] for MODIS Terra and Aqua L3. I will use it as comma-separated value (csv format) and planning to import it into QGIS for interpolating it conveniently to create maps with higher resolution (but of course with lower reliability due to this process) ?
Is it rational? Any idea or evaluation will make me glad,
Many thanks,
Kind Regards,
