Question: MODIS SST product

Re: MODIS SST product

For your most recent question, are you referring to a daily data product or a data product for a longer period (8-day or monthly)?

SST can provide data with some cloud cover (high clouds/cirrus) where there will be no visible range data.

Re: MODIS SST product

Hello, The "best" data product for your requirements is a more complex question. I am providing a couple of references (even though one is several years old) that discuss the issue. Because there are several causes of differences between daytime and nighttime SST, I do not think an average...

Re: MODIS SST product

Hello, One of the primary reasons is that in many places there will be a diurnal heating cycle due to warming of the surface skin layer by sunlight. It is also dependent on wind speed, as the heating effect of sunlight will be affected by wave action and mixing with the cooler waters below the surfa...

Re: CO2 build up rates and concentrations over North and South polar regions

John, Thank you for your comments. OCO-2 uses sunlight to perform its measurements, which limits coverage in the polar regions. "A set of eight measurements are made along a narrow ground track as the spacecraft travels about 2.25 km along its orbit track, providing spatial resolution of <3 km2...

Re: Importing data from giovanni to excel

Yes, this can still be done. For area-averaged time-series data, the output is still available as CSV, consisting of time/date and the value of the area average for each time increment. If you are seeking the values from the grid of a time-averaged map, we have a How-To document describing how this ...
