NOAA products are available via cloud resources as part of the NOAA Open Data Dissemination (NODD) program.

The NODD duplicates the data available on NOAA CLASS and is updated in near-real time. The program starts ~Oct 2022, so the entire record is not available.

It's straightforward to download real-time data using scripting languages like Python. The repository contains a simple sample script to query AWS for the NUCAPS OLR.

You will need python (I recommend Anaconda or Miniconda). You will also need the s3fs package. The installation syntax is below, type it into the Terminal (MacOS/Linux users) or the Anaconda Prompt (Windows users)

conda install s3fs -c conda-forge

You will need to open up the download_data.py file and edit the date product and date range that you are downloading. The script can be easilly altered to download another JPSS product.

select the product:

product = 'NOAA20_NUCAPS-EDR'
# other choices: NOAA20_NUCAPS-EDR, NOAA20_NUCAPS-CCR, NOAA20_NUCAPS-OLR

Update the date range:

year = 2023
month = 4
day = 22

start_time = '0000'
end_time = '2359'

You can also download the most recent data using:

# use today's date 
dt = datetime.datetime.now()
year = dt.strftime('%Y')
month = dt.strftime('%m')
day = dt.strftime('%d')

start/end hour-min
one_hour_ago = dt - datetime.timedelta(hours=1)

start_time = one_hour_ago.strftime('%H%m')
end_time = dt.strftime('%H%m')

Save and exit the script when you are done.

To run the script, simply type:

python download_data.py
