Due to changes at the data center which provides the NDVI data, we can no longer use the search method that was used by Giovanni to find the data according to the user specifications. NDVI data can be visualized with Worldview ( https://worldview.earthdata.nasa.gov ) , and the data is actually from ...

The daily data will usually have gaps due to satellite scanning patterns and conditions that affect data quality. I cannot provide a lot of insight on the OCO technique, except to note that because atmospheric CO2 is a well-mixed gas, it is computationally simpler to fill the gaps via assimilated da...

Hello. The Giovanni system has daily Level 3 CO2, NO2, and CH4 from the Orbiting Carbon Observatory, the Ozone Measuring Instrument, and AIRS, respectively. I have created a URL for these variables in Giovanni, provided below. Note that for CH4 from AIRS, a pressure level must be provided. 1000 hPA ...

The only chlorophyll data we are set up to support in Giovanni is the MODIS-Aqua Level 3 data product. To get higher resolution data from MERIS, VIIRS, or OLCI, you would have to contact the data provider. I hope you will be able to use Giovanni effectively.

Hello, Our apologies for the delay in this reply. Our MERRA-2 Subject Matter Expert has provided this preliminary answer with a request for more information. Over the ocean, both MERRA2 and ERA5 read in SST observations, Over land, ERA5 assimilates near surface air temperature and moisture, while ME...

I accidentally attached the "zoomed in" map twice.

You are welcome. OBDAAC personnel may be able to advise on cloud cover data in SeaDAS; there may be a cloud mask that can be generated or used in the system.

Hello, You can get this from the Giovanni system, https://giovanni.gsfc.nasa.gov/ , but you must input the geographical coordinates for the bounding box around the lake. I just attempted to do this, and I will provide the URL, along with a couple of images to show where the resulting data are locate...

Miguel, No, those are all in-water products. If you get a file with some ocean color data and some missing data, it is common for the missing data to be due to clouds, but it can also be due to the gaps between the MODIS scanning swaths, high aerosol concentrations in the atmosphere (dust can do thi...

Miguel, Both MODIS-Aqua and MODIS-Terra have a cloud fraction product, as well as AIRS. I don't know the best way to incorporate it for use with SeaDAS. I have provided a link to the Giovanni system at the GES DISC (not OBDAAC) that will allow you to examine it. The higher resolution Level 2 files r...
