Re: Looking for time-averaged Monthly chlorophyll-a estimations for Lake Apopka, FL
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.

Re: Cloud cover or similar data - Modis Aqua
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.

Re: Looking for time-averaged Monthly chlorophyll-a estimations for Lake Apopka, FL
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...

Re: Cloud cover or similar data - Modis Aqua
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...

Re: Cloud cover or similar data - Modis Aqua
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...

Re: Developing a real-time environmental monitoring platform with EOSDIS Data
Youssef, Thanks for your message. I am somewhat surprised you didn't receive a reply before now. I think your post may have been overlooked because you did not designate a particular data center. To get started, I would examine this site: https://lance.modaps.eosdis.nasa.gov/ The data latency for va...
