Python interface to RSIG Web API

pyrsig

pyrsig is a Python interface to the RSIG Web API. RSIG connects you to petabytes of air quality data from EPA, NASA, NOAA, and many other partners. pyrsig connects RSIG to xarray, pandas, and all your favorite python libraries.

Install

There are two easy ways to isntall pyrsig easily.

From pypi.org (most stable):

pip install pyrsig

From github (latest):

pip install git+https://github.com/barronh/pyrsig.git

User Guide

Many examples, tutorials, and guides are available at https://barronh.github.io/pyrsig. Only a few very basic examples are shown below.

Example

Get DataFrame for AQS ozone

import pyrsig

rsigapi = pyrsig.RsigApi(bdate='2022-03-01')
print([k for k in rsigapi.keys() if 'ozone' in k])
# ['airnow.ozone', 'airnow2.ozone', 'aqs.ozone', 'aqs.ozone_8hour_average', 'aqs.ozone_daily_8hour_maximum', 'pandora.ozone']
df = rsigapi.to_dataframe('aqs.ozone')
print(df.shape, *df.columns)
# (26760, 6) Timestamp(UTC) LONGITUDE(deg) LATITUDE(deg) STATION(-) ozone(ppb) SITE_NAME

Get DataFrame for PurpleAir PM25

import pyrsig

rsigapi = pyrsig.RsigApi(bdate='2022-03-01')
rsigapi.purpleair_kw['api_key'] = '<put your api key here>'
df = rsigapi.to_dataframe('purpleair.pm25_corrected')

Get DataFrame for TropOMI NO2

import pyrsig

rsigapi = pyrsig.RsigApi(bdate='2022-03-01')
df = rsigapi.to_dataframe('tropomi.offl.no2.nitrogendioxide_tropospheric_column')
print(df.shape, *df.columns)
# (303444, 4) Timestamp(UTC) LONGITUDE(deg) LATITUDE(deg) nitrogendioxide_tropospheric_column(molecules/cm2)

Get IOAPI formatted NetCDF TropOMI NO2

import pyrsig

rsigapi = pyrsig.RsigApi(bdate='2022-03-01')
ds = rsigapi.to_ioapi('tropomi.offl.no2.nitrogendioxide_tropospheric_column')
print(ds.data_vars)
# Data variables:
#     TFLAG      (TSTEP, VAR, DATE-TIME) int32 ...
#     LONGITUDE  (TSTEP, LAY, ROW, COL) float32 ...
#     LATITUDE   (TSTEP, LAY, ROW, COL) float32 ...
#     COUNT      (TSTEP, LAY, ROW, COL) int32 ...
#     NO2        (TSTEP, LAY, ROW, COL) float32 ...

Get List of Possible

import pyrsig

rsigapi = pyrsig.RsigApi()
keys = rsigapi.keys()
print(len(keys), keys)
# 80 ('airnow.pm25', ... 'aqs.ozone', ... 'cmaq.equates.conus.aconc.O3', ... 'hms.smoke',
#     'metar.wind', ... 'pandora.ozone', 'purpleair.pm25_corrected', ...
#     'tropomi.offl.no2.nitrogendioxide_tropospheric_column', ...
#     'viirsnoaa.jrraod.AOD550', ...)
keys = rsigapi.keys(offline=False) # slow and likely to many options
print(len(keys))
# 3875
