India - additional sources

[RocketD0g]

UPDATE: 20 Mar 2016: Please see my comment below (also timestamped 20 Mar 2016) for updated information and formatting of this issue.

Note: While several sources are listed, none are straightforward. If you'd like a straightforward new data issue, visit this issue for adding data sources from Tehran, Iran: https://github.com/openaq/openaq-fetch/issues/51

Below are listed potential other sources in India, contributed by the OpenAQ Community: These are listed as high priority because members of the community suggested them.

(1) http://www.cpcb.gov.in/CAAQM/frmUserAvgReportCriteria.aspx Note: Several Sites around India. I have not been able to access any data yet from this link with any combination of places I have put in. I'm also uncertain if it yields AQI or physical concentrations yet.

(2) http://164.100.160.234:9000/ Note: Several sites around India. These values are in AQI.

(3) http://www.cpcb.gov.in/CAAQM/mapPage/frmindiamap.aspx (same presumed sources as (1), just different view) Note: Several sites around India. To date, we've had issues programmatically accessing these data - something to do with a timeout issue perhaps? Do you recall,@jflasher?

(4) http://mpcb.gov.in/envtdata/demoPage1.php Note: Several sites around India. Looks like daily-averaged data. Unclear if data are available in real-time.

Hi,

I have suggested some of these sources which I know are not that easy. Thanks for creating the issue!

(1) What have you tried exactly? I attach an example of a query for which I could get data.

(2) A problem with the AQI is that one cannot get values for the past (at least I couldn't)

(3)Yes this is the same source as (1) but you also get the data availability. http://www.cpcb.gov.in/CAAQM/Auth/frmViewReportNew.aspx However I do not know how good it is (using it I could e.g. see when the 2 stations in Hyderabad started working but I haven't used it much).

Updating and reformatting from original issue above:

• Country of data source: India
• Specific coverage within country: Several cities within India
• URL: The url's of interest are nested and laid out accordingly:

Map with coverage across India from CPCB: http://www.cpcb.gov.in/CAAQM/mapPage/frmindiamap.aspx

Clicking on a state, there is finer, city-level coverage on the map. Example: http://www.cpcb.gov.in/CAAQM/mapPage/frmuttarpradesh.aspx?stateID=28

Then, clicking on a given city, a pop-up will be generated that gives a choice of accessing data or station details (e.g. coordinates) for a list of stations within the city (example): http://www.cpcb.gov.in/CAAQM/frmStationdetails.aspx?cityID=136

Data for a given station is shown as (example): http://www.cpcb.gov.in/CAAQM/frmCurrentDataNew.aspx?StationName=BTM&StateId=13&CityId=136

• Pollutants measured: Differing combinations of PM10, PM2.5, NO2, CO, SO2 (perhaps others)
• Are units of measurement clearly indicated (e.g. do you see 'AQI', 'ppm' or 'ug/m^3'?) Note: We cannot directly input AQI, API, AQHI, etc. values directly into our system. Yes
• Comments about units: [ex. 'They are viewable on {this page}, see the table] They are clearly listed in the table.
• Are there date+timestamps for pollutant measurements? Yes, and please note ,they are in running 24hr averages.
• Are time intervals otherwise indicated on the site (e.g. 'Measurements are 15 minute averages'): Yes, 15 min intervals.
• Are coordinates for the stations clearly indicated or discernible? Comment. (e.g. do you see a map or a list of coordinates): Yes, these are viewable when you click on the "view details" page here: http://www.cpcb.gov.in/CAAQM/frmStationdetails.aspx?cityID=136
• Are you with the host agency and may we contact you?: No.
