Re: MODIS SST product

Thank you for the answer. Regarding the MODIS resolution at nadir is 1 km, why the resolution of MODIS products like chlorophyll-a, sst, and others are different from the sensor resolution of MODIS itself? For instance, the resolution of monthly SST Aqua MODIS level 3 is 4 km while the sensor resolu...

Re: MODIS SST product

What do you mean by SST can provide data with some cloud cover where there will be no visible range data?

Thank you for the answer. Following your answer, how can the SST product level 3 of MODIS Terra/Aqua have a SST value while there are lots of cloud cover especially in the tropical area?
What kind of cloud-removal algorithm is applied in the SST product level 3 of MODIS Terra/Aqua?

Re: MODIS SST product

Thank you for your answer. My further question is, if MODIS Aqua provides night and daytime SST products then if we want to take daily SST, which product should we select? night or daytime? or can we just consider an average of night and daytime SST products as the daily SST?
