download MODIS data

by marcolaiolo » Tue Jul 25, 2023 8:51 am America/New_York

Dear Staff,
after long time I have to download Level1b data from LAADS Archive (MOD03 and MOD021KM, respectively). Firstly, I request and generate a new token; however inserted in my matlab code to download these kind of products I write this:

system (['wget -e robots=off -m -np -R .html,.tmp -nH --cut-dirs=9 "',...
foldername,'/',file,'" --header "Authorization: Bearer ',LAADS_token,'" -P ',...
nasatemp_folder]);
where
>> foldername

foldername =

'https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/61/MOD03/2023/126'

file =

'MOD03.A2023126.0905.061.2023127012714.hdf'

>> nasatemp_folder

nasatemp_folder = local temporary folder before being complete the download

Today, the response to this command has been:

https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/61/MOD03/2023/126/MOD03.A2023126.0905.061.2023127012714.hdf
Resolving ladsweb.modaps.eosdis.nasa.gov (ladsweb.modaps.eosdis.nasa.gov)... 198.118.194.40

HTTP request sent, awaiting response... 504 Gateway Time-out
Retrying.

I know that it can be seriously difficult for you to understand this issue; but you can suggest me, also only in theory if there is some error in my command (also the --cut-dirs=3 dpesn't work) or there is some problem (e.g. because too connection) in the connection from the https address.

Thank you in advance for your precious work and assistance,
Marco Laiolo
