Introduction

The Clidata system is primary intended for archiving of climatology data, for the data quality control and for administration of climatology stations and station observations. The System was designed to replace the old CLICOM system, which has been used in Czech Republic from 1993-2000.

The system is designed for the Oracle database environment, which defines simple and secure access to stored data.

By virtue of the system flexibility, easy administration and multi-language support, the system is capable of  set up in any foreign country and for any meteorological service. The system has been  operationally used in Czech Hydrometeorological Institue for 5 years and it is successfully installed in more than 11 other countries. 

The system is particularly user-friendly  during the definition of stations, station observations and manual key entry of the data. The system facilitates the population of data from automated (real-time) stations as well as the definition of personalised key entry forms.

Main Features Of The System

The Clidata system provides the definition of: The database can store these kinds of data:
  • Daily observed data and daily data measured by automatic stations
  • Observation of meteorological phenomena
  • Monthly data (which has not been calculated from daily data)
  • Upper air data (ascent data)
  • Long term rainfall gauge measurements (rainfall accumulations)
  • Normals (which have not been calculated from daily data)
  • One minute precipitation totals (rainfall intensity)
The system automatically calculates these kinds of data:
  • Daily data (according to calculation formula)
  • Monthly/Yearly data (max, min, sum, average and conditional day count
  • Long term normals
  • Long term extreme values
  • Interpolation of missing values
  • Inventory of missing data
For input of data the system uses: Additional calculated products: Additional features of the system:
