GCW Station Application Process
GCW welcomes the contribution of any station that makes measurements of the cryosphere. Its goal is to design a network that advances WMO’s scientific and operational objectives. The process of evaluating a station or a cluster for inclusion in the GCW surface network is described below. It is the same for stations and clusters, core (CryoNet) and contributing, unless indicated otherwise.
- A representative of the station or cluster (hereafter, the “applicant” and the “station”) completes and submits the station questionnaire (the “application”) on the GCW website (globalcryospherewatch.org/cryonet/questionnaire).
- It is recommended, though not required, that the applicant present the station at a GCW meeting before beginning the application process.
- By submitting the application for a core station, the applicant is implicitly agreeing that the station meets the CryoNet Minimum Requirements. A commitment to longevity, data quality, and data distribution is particularly important.
Each CryoNet station will be evaluated annually to ensure that it continues to meet the Minimum Requirements. If it does not, a timeline for correcting deficiencies will be mutually agreed upon by the Team and the station representatives. If no agreement can be reached, the station will be removed from the CryoNet network or, by mutual agreement, will become a contributing station.
A change in the station type, core or contributing, requires reapplication. This entails a modification to the original application, resubmission, and re-evaluation by the Team and GSG. It does not require approval by EC.
Stations may be withdrawn at any time from the GCW surface network by request, in writing, of the station owners/operators.
When an application is submitted via the online questionnaire process, the station is listed on the GCW website as “candidate”. It is not yet part of the GCW surface network. When the GCW Steering Group recommends stations for inclusion in the surface network, for all practical purposes they are part of the GCW network and will be listed on the website accordingly. They are not, however, officially part of the network until approved by EC.
1To ensure a unique, high-quality network of surface observations, stations and clusters are evaluated for inclusion in CryoNet based on several factors. Fulfilling the minimum requirements does not in itself guarantee acceptance as a CryoNet station. Other criteria that are considered by the CryoNet Team when evaluating applications include (1) the number of recommended variables that are measured (see the lists), (2) the continuity and length of the data record, (3) the extent to which data are available and accessible, (4) sustainability of the station, (5) conformity to GCW best practices, and (6) the location and representativeness of the proposed station relative to the geographic distribution of existing CryoNet stations.
