Dear User,

I just did a test and no issue to download the data (can display in Panoply correctly). Could you please give another try? Sometimes, hiccups like this happen due to too many people trying to download IMERG data.

Thank you for your response!
It happens when I use GES DISC Subsetter. Now, I use OPeNDAP and I'm able to download data via the latest version of wget 1.21.4. However, there is a jump! It downloads one day, then skip one day and then downloads the third day. There is an error of "unable to establish ssl connection.". Please take a look at the attached file. Thank you for your consideration!

Please be aware that the IMERG Daily are already in nc4 format, and it is best to downloaded in full, as given by search engines, unless variable/spatial subset is needed. Hope this helps.

Thank you for your response! How can I download them in full?
I have them in a text file and when I use this code:
wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --keep-session-cookies --user=<your username> --ask-password --content-disposition -i <url.txt>
I get that error of "unable to establish ssl connection."

The easiest is to navigate from the product page, where the "Subset/Get data"
is very visible on the right:

Thank you for your response! Yes, I clicked on "Subset/Get Data" and then I clicked on "Download Links List" and when I have that text file, I run the script:
wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --keep-session-cookies --user=<your username> --ask-password --content-disposition -i <url.txt>
Then, I get the error:
"unable to establish ssl connection."

Hi, We need the original simple text file with the list of the data links. It has
the job id in the file name, like:
https://disc.gsfc.nasa.gov/api/jobs/results/6491e3abe482352e3ff0ada1
so we could download it.

We can't use the PDF file because it has special symbols, hyphens "-", instead
of dashes"-" in the file names, and it is not clear where this conversion took
place.

Also, do not use "--content-disposition" when no subsetting is required.
