General definitions

In the scope of the Copernicus Climate Change Service (C3S), a Thematic Climate Data Record (TCDR) has a fixed end point, whereas an Interim Climate Data Record (ICDR) is extended continuously. The TCWV_MERIS_SSMI_TCDR product is a TCDR which consists of two satellite-based estimates of the Total Columnar Water Vapor (TCWV) of the atmosphere. TCWV is a measure of the total water vapor content of the atmosphere over a certain area [kg/m2] and is also referred to as Precipitable Water Vapor (PWV) or Integrated Water Vapor (IWV).

5.1 Enquiries

The user (customer) can has the possibility to browse and search in the Copernicus Knowledge Base on Copernicus Climate (CKB) (CAMS and C3S Knowledge Base (CKB)) or the Copernicus Climate Data Store desk (https://cds.climate.copernicus.eu/contact-us). This is known as the level-0 process of User Support.

service desk

If the level-0 support fails to answer the user's query, they may then make a request, which is sent to Once a request is sent, the Copernicus User Support (CUS) Service team at ECMWF will handle the requests within 8 hours . These (level-1) requests will be handled within 8 hours.

For any scientific and special specialist enquiries that cannot be answered by the CUS team at ECMWF or addressed to by the Copernicus Knowledge Base, the request will be forwarded to the Copernicus User Support Specialists (level-2) to the following email address:

.

...

Enquiries forwarded to the Copernicus User Support Specialist team at DWD will be acknowledged within 3 working days (target 100%) and a notification is sent to the user. This step is handled on the JIRA

Footnote

JIRA: Project management software tool created by Atlassian company

performed via the JIRA1 Service Desk established at ECMWF for the current project. In case of specific scientific issues, the enquiries will be channeled to the ECV and data specialist of the C3SC3S2_312b312a_Lot1 project and should be resolved within 3 working weeks (target 85%). In case of brokered datasets, the data specialist may choose to contact the responsible team at the provider level if they cannot resolve the issue on their own. In each yearly quarter, we aim for User Support satisfaction scoring " 3 " in 90% of all voluntary based feedbacks by users, with " 1 " (very unsatisfied) to " 5 " (very satisfied). We will also list the number of tickets in the Quarterly Report.

5.3 Service availability

User support and system maintenance will usually be available only during regular working hours in Germany, i.e. Monday–Friday, 9:00–17:00 CET, respectively, excluding public holidays.

5.4 User forum

The user forum for C3S_312b_Lot1 Atmospheric Physics has recently been established. It is now online and available by using the following link:
