| Introduction |
|
This web site is a managed list of unique station identifiers to identify surface sites operating within Global Atmosphere Watch (GAW) as well as other programmes.
It also serves as the clearing house for registering such identifiers for sites not (yet) affiliated with GAW.
The initial focus is on ground-based fixed stations.
The goal is to assign a unique 3-letter code to each known station with a long-term atmospheric monitoring purpose.
This process should be based on consensus as much as possible.
We invite the community to participate, because we would like these codes to find acceptance.
Your assistance is essential! Please share this web address with anyone you know might have a stake in this process. |

Please direct any question you might have to the GAWSIS administrator (gawsis@empa.ch). |
| Why 3-letter codes? |
|---|
|
The reasons for choosing 3-letter codes as unique station identifiers were 1) They are relatively easy to remember. 2) They have been and are being used in a number of programs already. 3) There are 17576 unique possibilities based on a 26-letter alphabet, which should be sufficient to accomodate existing and new stations for the foreseeable future. |
| Initial assignment of codes |
|---|
|
Codes have been assigned initially to sites registered in GAWSIS if 1) they participate in the NOAA/ESRL flask sampling network, or 2) they have submitted data to the World Data Centre for Greenhouse Gases (WDCGG), or 3) they participate in another international program that uses 3-letter codes. In case of conflict, the assignment was done using the above precedence, or - in rare cases - by decision of the GAWSIS manager. |
