Hi Gail, I am trying to download ocean IOP MODIS-AQUA, and other sensor data, from the earth.data.nasa.gov/oceancolor.gsfc.nasa.gov site. This is a typical wget command I am using at the Windows command prompt: wget --user=anthcook --ask-password --auth-no-challenge=on https://oceandata.sci.gsfc.nas...

Hello all, In the past, I have done a manual extraction(subset) of MODIS-AQUA data using the online Level3 browser with manual inputs. I would now like to do the same type of download, except in an automated fashion with wget via Windows. Is there a way to build a wget command to do a download of MO...

mgreene, The results of wget -V are copied below. Is this a sufficient wget and SSL version?

Could someone explain the "NRT" designator in the file naming convention, in more depth than the description "Near Real Time"? For example, on Nov 1, 2022, there is an NRT version and a non-NRT version available: AQUA_MODIS.20221101.L3m.DAY.IOP.bb_531.4km.nc 2023-01-31 AQUA_MODIS...

Hello mgreene, I attempted the MERRA2 download again, and am still getting the "unable to establish SSL connection" error. Am I making any syntax errors in the MERRA2 request? Below is the Windows command line response to my unsuccessful MERRA2 request. As a sanity check, I also did an AQU...

Sean, Thank you; makes sense. Now that I am aware, and at least from my perspective, there is no need for any further tweaking on your end. I'm also still wondering why I had one successful MERRA2 download with wget, but for all other (many attempts), it fails to establish an SSL connection? Are the...

Sean, Great catch, thank you. Whether or not I use the password credentials in the wget command, the result is a file with the .nc extension: AQUA_MODIS.20211202.L3m.DAY.SST4.sst4.4km.nc However, the size of the .nc file is only 13kB without the pwd credentials, and is 10MB with the credentials. Sin...

I am fairly certain that I was running a version of wget that is later that ver 1.18, but to be sure, I downloaded ver 1.21.3, 64bit. If I am reading the download information correctly (see attachment), ver1.21.3 was compiled with OpenSSL 1.1.1m. Upon the attempt to download MERRA2 data with wget ve...

Thank you, I will check my wget version and investigate the other versions you mention if that seems to be the issue. Back to the original post, can someone also help me understand why I can download the MODIS-Aqua file either with or without the password functions embedded in the wget line? Are pas...

Hello all, I am new at using wget for downloading data from a Windows command prompt using wget. I was able to generate a user/password cookie file using either of the the two commands: wget -qO- --keep-session-cookies --save-cookies cookies.txt --post-data --user=USERNAME --ask-password https://urs...
