Dear Sunanda,

You need to make the GEO files with modis_GEO.py.

Hi,

I'm glad you got it working.  Thanks for the pointers to other services.
It's always helpful to see what strategies others use to distribute data.

Hi,There is still some confusion about dates in your message.  April 29, 2017 is the119th day of the year, so corresponding file names would start with "A2017119".File names starting with "A2017105" contain data from April 15, 2017.A colleague of mine pointed out that the fi...

Hi,Your computation of dat yields a day that is one day too early for me because the datecommand is using the local time zone and January 1 is during standard time, butApril 15 is during daylight saving time.  (Your location may have different time rules.)Why not just avoid the issue altogether...

Hi,The browse code was not explicitly set up for this, but it is possible with a littleparsing of the html that the browser sends back.  If you are using bash or a similarshell, the following example will download Aqua/MODIS level-2 files that coverthe Argentine Sea in 2018.url=https://oceancol...

Sorry.  I got my sensors mixed up.  Glad you figured it out.
