Key Error #7
Description
I am hoping to use this package to download data. I have changed some of the variables to download the data in the regions and collections I need. However, whenever I run the example download script I get a Key Error. I am a Windows user and below is my code.
class dummy_downloader():
def setUp(self):
# SIMPLE USE CONFIGURATION
## The user should define the input parameters in this script for the easiest use case of the package
# specify your user authentication
self.username = input("Please Enter Your USERNAME:")
self.password = getpass("Please Enter Your PASSWORD: ")
# specify the date range
self.initial_year = 2018
self.initial_month = 1
self.initial_day = 1
# specify the end date
self.final_year = 2018
self.final_month = 1
self.final_day = 3
# specify the bottom left corner of the rectangular region
self.lat_1 = 30.36
self.lon_1 = -85.03
# specify the top right corner of the rectangular region
self.lat_2 = 35.2
self.lon_2 = -81.25
# specify the number of threads, this is the number of instances that will run at the same time
# theoretically, this can be as many as you think your machine can handle, though GESDISC may
# impose a limit
self.thread_num = 5
# specify the output destination of the data, depending on operating system changes the file separator
# default location is where you run the script, specify here if you want to change it using os.join.
self.output_dir = os.path.join(os.getcwd(),"MERRA2_data")
# specify the merge timelapse of the data
# select from 'none', 'daily', 'monthly', 'yearly'
self.merge_timelapse = 'monthly'
# Here you can change what actually gets downloaded
# full list of variables can be founnd here https://gmao.gsfc.nasa.gov/pubs/docs/Bosilovich785.pdf

Any help would be greatly appreciated!
