How to get all the eMAS granule names from the ORACLES campaign using python 3 ?

Example of how to get all the (MODIS Airborne Simulator) eMAS granule names from the ORACLES campaign using python:

Get ORACLES campaign days

First step, let's download, using python, the json file at the root of the eMAS ORACLES campaign available here:

import urllib.request, json

ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES.json'

with urllib.request.urlopen(ladsweb_url) as url:
    data = json.loads(url.read().decode())

print(data)

which returns

[{'name': '16_953', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_954', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_955', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_956', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_957', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_958', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_960', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_961', 'size': 0, 'last-modified': '2018-10-03 23:10'}, {'name': '16_962', 'size': 0, 'last-modified': '2018-10-03 23:10'}]

Get file names for a given day

Get eMASL1B file names

ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/16_953/eMASL1B.json'

with urllib.request.urlopen(ladsweb_url) as url:
    data = json.loads(url.read().decode())

print(data)

returns

Get eMASL2CLD file names

ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/16_953/eMASL2CLD.json'

with urllib.request.urlopen(ladsweb_url) as url:

Create a loop over all ORACLES campaign days

Next step create a loop over all ORACLES campaign days:

for day in data:
    print(day)
    print(day['name'])

    ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/{}/eMASL1B.json.json'.format(day['name'])

    with urllib.request.urlopen(ladsweb_url) as url:
        eMASL1B_data = json.loads(url.read().decode())

    ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/{}/eMASL2CLD.json'.format(day['name'])

    with urllib.request.urlopen(ladsweb_url) as url:
        eMASL2CLD_data = json.loads(url.read().decode())

Example of python code

import urllib.request, json

ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES.json'

with urllib.request.urlopen(ladsweb_url) as url:
    data = json.loads(url.read().decode())

granule_name_list = []

for day in data:
    print(day)
    print(day['name'])

    ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/{}/eMASL1B.json.json'.format(day['name'])

    ladsweb_url = 'https://ladsweb.modaps.eosdis.nasa.gov/archive/MAS_eMAS/ORACLES/{}/eMASL2CLD.json'.format(day['name'])

    with urllib.request.urlopen(ladsweb_url) as url:

    for eMASL1B,eMASL2CLD in zip(eMASL1B_data,eMASL2CLD_data): 
        granule_name_list.append((eMASL1B['name'],eMASL2CLD['name']))


print(granule_name_list)
