Data processing

[madhusmita]

Hi all
I want to download and process the data for a particular date range.
I tried by using this following code:

echo "Fiename: $line"
echo ""; echo ""; echo " "; echo " ";
wget --user=xxxxx --password=xxxxxx --auth-no-challenge=on https://oceandata.sci.gsfc.nasa.gov/echo/getfile/$line
done<$HOME/chandan/Modies_aqua/MODISA/Yyear/Yday/L1/L1_File_List_$Yyear$Yday.txt

The data is downloaded and processed for only one date (one day). For other dates only the text file is coming.

Can anyone please suggest how to download the data for multiple dates using wget.

Thanks in Advance:smile:

You have left out key portions of your script, but here is a method that works for me to download Aqua/MODIS L1 files for the month of January 2020.for f in `wget -q --post-data="sensor=aqua&sdate=2020-01-01&edate=2020-01-31&dtype=L1&results_as_file=1&addurl=1&std_only=1" -O - https://oceandata.sci.gsfc.nasa.gov  wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --content-disposition $fdonePlease see https://oceancolor.gsfc.nasa.gov/data/download_methods/ for more information.Regards,Norman

You can generate a list of URLs for files to download by using our L1 browser.
Specify your region and time period of interest, click "Find swaths", and then click "ORDER DATA" and follow the instructions.  You can get more information by clicking on the "Help" button.
