Add Realtime AWS Feature

[scottthomaswx]

I did not, but I did find a workaround by pulling for the day instead of the last hour and just pulling bottom of the stack/most-recent with exceptions built in to handle crossing 00z.

Pretty basic script to grab the latest file if of interest, but would obviously take some mods.

from datetime import datetime, timedelta
import os
import tempfile

import nexradaws

# start connection
conn = nexradaws.NexradAwsInterface()

# get the time and an earlier time
rightnow = datetime.utcnow()
rightthen = rightnow - timedelta(hours=1)

# what radar ya interested in?
radarid = 'KFWS'

# query the scans
thescans = conn.get_avail_scans_in_range(rightthen, rightnow, radarid)
#print(thescans)

if len(thescans) > 0:
    # create a temporary directory or replace with path you want
    templocation = tempfile.TemporaryDirectory(dir=os.getcwd())

    # get the most recent
    localfiles = conn.download(thescans[-1],templocation.name)
    print(f"file saved to {localfiles.success[0].filepath}")
else:
    print(f"Sorry no scans found for query{rightthen} - {rightnow}")

Just realize you might need the changes I put in the open pull request for this to work properly though... :/

I did try this, including setting the 'now' time to just before the current time and yet I'm still getting none-type errors

Just to verify, did you pull the changes mentioned in this merge request #15 ( the stack is in my fork https://github.com/nguy/nexradaws/tree/master).

If so, can you past the error trace to see if it's a different failure mode?
