California AQ data from CARB

[RocketD0g]

Below Response from California Air Resources, regarding programmatic access to their AQ data.

It would be helpful if this response were investigated for:

• access to station-level locations/coordinates
• Other items required by the OpenAQ Data Format
• best way of all of these options to access real-time information (e.g. preliminary vs verified data) that can be ingested into the system.

We currently do not have an API for AQMIS data. You can however obtain hourly near real time ozone and PM25 data updated between 42-45 minutes after the hour at the following URLs:

https://www.arb.ca.gov/aqmis2/download/ozone/ozone.csv

https://www.arb.ca.gov/aqmis2/download/pm25hourly/pm25hourly.csv

We also have a snapshot of our ADAM and AQMIS database starting from 1980 in a zip file you can download here (1Gb in size):

 * Please note that the above data set contains a mix of preliminary and verified data - see the 'ReadMe.txt' file included in the above data set for more information.

If you require Met data it can be downloaded her (5Gb in Size):

We also have two online databases that provide air quality data:

 1.   The Air Quality and Meteorological Information System (AQMIS) is a web-based source for real-time and official air quality and meteorological:      https://www.arb.ca.gov/aqmis2/aqmis2.php.  Air quality data can be viewed and downloaded using the “Air Quality Data” button.  Use the “Special Reports” tab to     download the data.

 2.   The Aerometric Data Analysis and Management System (iADAM) website:  https://www.arb.ca.gov/adam/index.html provides official air quality data and statistics.

We also have a link to the State and National Ambient Air Quality Standards: https://ww3.arb.ca.gov/research/aaqs/aaqs2.pdf

@sruti Still high priority, Can I start work on it or someone working on it?

@ahmedalawady sruti is no longer at OpenAQ. After a quick look at this set it seems some and perhaps all these locations are already ingested by OpenAQ via the EPA AirNow adapter. If there are some in this CARB set that arent currently captured, I'd be open to investigating this further, otherwise will likely close this issue.

Thanks, @russbiggs for your reply, I will go through the issues again to pick another one, I am interested to contribute so if you have any issue high priority or suitable to new-contributor please mention me on it, Thanks :)

@ahmedalawady we're doing some pretty major changes on this repo currently. Once we have it updated it will be in better position for contributions. If you would like to review other PRs to see if they are still valid data sources and/or are not already in OpenAQ that would be a helpful way to contribute for now.
