Python Email Data Entry

The following code can gather data from weather stations reporting to the CHORDS portal, package it up into the proper format for GLOBE Email Data Entry , and send it using the SparkPost API.

In order to send email, you'll need to setup SparkPost by creating an account and confirming you own the domain you'll be sending emails from. You'll also need to create a SparkPost API key and set the environment variable SPARKPOST_API_KEY equal to the value of your API key. This script can be further modified to use a different method for sending email if needed.

This code will contact the CHORDS Portal and collect all the measurement data from the specified instrument, in the specified date range.



In [34]:

    
import requests
import json


r = requests.get('http://3d-kenya.chordsrt.com/instruments/2.geojson?start=2017-03-01T00:00&end=2017-05-01T00:00')
if r.status_code == 200:
    d = r.json()['Data']
else:
    print("Please verify that the URL for the weather station is correct. You may just have to try again with a different/smaller date range or different dates.")

Now the collected data can be viewed simply by issuing the following command



In [25]:

    
d









    Out[25]:





[]

This code is useful for looking at a specific measurement dataset



In [ ]:

    
for o in d:
    if o['variable_shortname'] == 'msl1':
        print(o['time'], o['value'], o['units'])

A modified version of the above code will format the data properly for GLOBE Email Data Entry



In [30]:

    
davad_tuple = (
    'f1',
    'f2',
    'f3',
    'f4',
    'f5',
    'f6',
    'f7',
    'f8',
    'f9',
    'f10',
    'f11',
    'f12',
    'f13',
    'f14',
)

def make_data_set(d):
    data_list = []
    for o in d:
        if o['variable_shortname'] == 'msl1':
            t = o['time'].split("T")
            tdate = t[0].replace('-', '')
            ttime = ''.join(t[1].split(':')[:-1])
            pressure = o['value']
            if ttime.endswith('00') or ttime.endswith('15') or ttime.endswith('30') or ttime.endswith('45'):
                davad_tuple = ['DAVAD', 'GLID4TT4', 'SITE_ID:45013']+['X']*11
                davad_tuple[3] = tdate + ttime
                davad_tuple[13] = str(pressure)
                data_list.append('{}'.format(' '.join(davad_tuple)))
    #print('//AA\n{}\n//ZZ'.format('\n'.join(data_list)))
    return data_list

To see the data formatted in GLOBE Email Data Entry format, comment out the return data_list command above, uncomment the print command right above it, then issue the following command



In [ ]:

    
make_data_set(d)

To email the data set to GLOBE's email data entry server, run the following code.



In [8]:

    
def email_data(data_list):
    import os
    
    from sparkpost import SparkPost
    
    FROM_EMAIL = os.getenv('FROM_EMAIL')
    BCC_EMAIL = os.getenv('BCC_EMAIL')

    # Send email using the SparkPost api
    sp = SparkPost() # uses environment variable named SPARKPOST_API_KEY

    response = sp.transmission.send(
            recipients=['data@globe.gov'],
            bcc=[BCC_EMAIL],
            text='//AA\n{}\n//ZZ'.format('\n'.join(data_list)),
            from_email=FROM_EMAIL,
            subject='DATA'
    )

    print(response)

Finally, this command sends the email



In [35]:

    
email_data(make_data_set(d))
