GOP-TropDB - TropModel online service

------------------------------------------------------------------------------
NOTICE: The ERA-interim data were discontinued by the ECMWF at the end of August 2019.
The service will be updated to a new system supporting ECMWF's ERA5 or NCEP's GFS data.
We appology for any inconvenience this may cause.
------------------------------------------------------------------------------

The form serves for calculation of site-specific tropospheric parameters, vertical reduction parameters, conversion factors or other auxiliary meteorological parameters for scientific applications.

The following limitations for the service are currently applied:
Scope: 100 sites; Period: 366 days (1 year); Sampling: 1s - 21600s (6h); Interval: 1990 - present (delayed by 2-3 months);

Notes & Updates:

• 2016-01-15: Software upgrade (back-end). Revised models and more data outputs enabled.
• 2016-01-15: Web-interface upgraded (front-end). Unofficial Tro-SINEX output enabled.
• 2016-12-13: Software upgrade [1.1]. Fixed negative WV pressure and specific humidity. T,E surface re-adjustement.
• 2017-02-07: Software upgrade [1.2]. Prototype support for SINEX_TRO V2.0. Added pressure scale height.
• 2020-xx-xx: Software upgrade [1.3]. Upgraded system. Availability of ECMWF ERA5 data set.
