Problems to untar file with MODIS PAR L3 images

by laurare » Wed Aug 04, 2021 1:52 pm America/New_York

Hello,

last week I tried to download daily MODIS PAR l3 images from https://oceancolor.gsfc.nasa.gov/l3/
I clicked on "extract or download l3 data" bottom to reduce the region and period of time. I got the order I wanted with the manifest.txt file, and I did the same as last time when I downloaded MODIS chla data with Python:

# Download PAR data
import wget
import tarfile

output_directory = '/Users/laurare/OneDrive - cima.fcen.uba.ar/PICT-2017-2386_Cele/PAR_modis'

url = 'https://oceandata.sci.gsfc.nasa.gov/cgi ... sted_files'

file = wget.download(url,output_directory)
tar = tarfile.open(file,'r:*')
tar.extractall(path = '/Users/laurare/OneDrive - cima.fcen.uba.ar/OneDrive - cima.fcen.uba.ar/PICT-2017-2386_Cele/PAR_modis/')
tar.close()

However, this time I couldn't open the tar file. I thought it may be a mac problem, so I asked a colleague to try in linux, then on ubuntu and I also tried using wget and tar on linux terminal instead of python. I even reduced the period of time, hoping that the problem was related with the size of the file, and nothing worked.
I also thought that I wasn't downloading the file properly and I tried to use the appkey:

url = 'https://oceandata.sci.gsfc.nasa.gov/cgi ... 3bd4174e9f'

Any help is welcome. Thank you!
Laura
