SondeHub maintains a database of radiosonde launch sites, including information on radiosonde types used, frequencies, launch times, and other useful information. This information is used to show launch site information on the sondehub.org map, and allow flight path predictions for future launches to be generated.

Finding Site Information

Probably the easiest way to look for sites that we know about is to look on the https://sondehub.org/ map. Sites can be clicked on to bring up details:

The entire site database is available in JSON format via this API: https://api.v2.sondehub.org/sites

Suggesting updates or additions to the Site database

To suggest a new site be added, please use the Google Form here: https://forms.gle/GserZmFAif5z9QXH9

To suggest updates to an existing site, please use the 'Contribute here' link on the site popup on sondehub.org, which will pre-fill a lot of the site information for you.

Site suggestions are manually reviewed and added into our database. This requires a lot of verification of submitted data, and it can take a few weeks for suggestions to be actioned.

When you submit a suggestion via our form, it will be added as a comment to this issue: https://github.com/projecthorus/sondehub-tracker/issues/114

Once processed, the comment will be hidden with a reason:

• Resolved - Suggestion actioned.
• Duplicate - Suggestion was a duplicate, or very similar to a previous suggestion.
• Spam / Off-Topic - Suggestion included obviously incorrect or invalid data.

Please take note of the following points when requesting updates or additions:

• We record site launch times as their 'nominal' sampling time (e.g. 00Z, 12Z). This usually means that the sonde is actually launches up to an hour before this. Please do not request a change from this nominal launch time to the actual launch time.
• The descent rate that we record is the descent rate on landing.
• Please be patient and do not submit site suggestions more than once! If there is some reason that a site should be added urgently, then contact us at support@sondehub.org

Site Suggestion Process

The Google Forms responses are all saved in a Google Sheets document and a Apps Script function runs for each new response which formats the data and posts it as a new comment to the GitHub issue.

It might be a good idea to upload the script somewhere...

I also wrote this a few months ago which goes into some more details: https://lukeprior.github.io/blog/posts/sondehub-suggestions/

The GitHub issue comments have a different formart depending on whether they are for a new site suggestion or existing site modification.

All issues will include a map with the proposed location which can be used as a quick sanity check.

For existing sites I have included the entry in a code block for reference.

The suggested code should be correct in most cases and is generated by the Apps Script using the provided values. (have to manually do some times if non standard and obscure radiosonde types)

If it's a modification I also attempt to show the difference between the two outputs which is handy to quickly check.

So once I've verified that the changes/suggestion seem valid I take the output from View suggested.

The OpenSearch Dashboard (https://github.com/projecthorus/sondehub-infra/wiki/ElasticSearch-Kibana-access#access) is used to update/modify the site list.

Open the Discover page and select the sites dataset, also open the Dev Tools page.

For the site that needs updating find its entry on the Discover page by creating a filter on the station ID. Then copy the _id for it.

To upload a new entry to dataset the following command is used in Dev Tools

https://es.v2.sondehub.org/_dashboards/app/dev_tools#/console

POST sites/_doc
{
    "station": "72659",
    "station_name": "Aberdeen, Aberdeen Regional Airport (United States)",
    "position": [
      -98.4133,
      45.4556
    ],
    "alt": 396,
    "rs_types": [
      "54"
    ],
    "times": [
      "0:00:00",
      "1:12:00"
    ],
    "burst_altitude": 34000
  }

Then the upload can be verified by refreshing the Discover page and checking that two entries exist when finally the old version can be deleted by using the following command in Dev Tools with the _id.

DELETE sites/_doc/T9lAXoMBCj_oAeeec47q

Radiosonde Frequencies

Radiosonde frequencies can be included in the rs_types entry as follows:

    "rs_types": [
      ["54", "403.610"]
    ],
