AIRNow Web Services:

Why Are They Needed?


Web Services provide a way to retrieve data and
information ‘on demand’ from the AIRNow system.


Forecasts


Action days


Observed data


Multiple format options including maps


Agency, reporting area, and monitoring site information


Uses


Agency websites, web developer access


Local news organizations


Other agencies


Schools and researchers


Spreadsheets and other applications


The public

AIRNow Web Services


Where we’ve been


Simple Object Access Protocol (SOAP): not
as simple or clean as it sounds


Progress in 2009


A RESTful approach


The future


an AIRNow Application
Programming Interface (API)


Additional services, data sets, and formats
useful for building applications


An easier to use, well
-
documented interface

AIRNow Web Services:

A
RESTful

Approach


Example question: “What is the current air
quality forecast for my home town ZIP Code?”


URL:

http://ws.airnowgateway.org/GatewayWebService
REST/Gateway.svc/
forecastbyzipcode?key
=43321E
-
F56Q
-
B612
-
68FBN&zipcode=95401&format=
csv


Looks complicated, but let’s break it down


ForecastByZIPCode

= the name of this request*


Key = unique user key


ZIPCode

= ZIP Code of interest


Format = payload options (CSV, JSON, KML, XML, etc.)


Optional: Date = any date of interest (defaults to the
current date)

*a companion service exists for observed data:
ObservedByZIPCode
