National Climate Observing System

Il contenuto di questa pagina è attualmente disponibile solo in inglese.

Climate observation is constantly developing driven by evolving user requirements and technological advances. Internationally this is reflected in the periodic updating of the GCOS Implementation Plan. In Switzerland, MeteoSwiss recently published a new GCOS Switzerland Strategy for the period 2017 - 2026.

Currently, 33 essential climate variables, two ancillary datasets and six international centres operated by Swiss institutions, are included in the inventory report. For each variable, the type of observations carried out in Switzerland, the legal basis, the  importance, and international significance of long time series are described.

In addition, the report identifies time series and international centres that are at risk of being discontinued due to inadequate financial resources.

Observation system

A climate observing system fulfilling the diverse needs of its users relies on a variety of observing techniques. The continuation of the existing long-term in-situ measurements will continue to be of fundamental importance for global climate observation.

At the same time, new measurement techniques are becoming available thanks to significant advances in technology and scientific methodology. For example, new satellites are launched further expanding the nearly 50-year long historical satellite climate data records. The inventory report also includes a chapter describing new trends climate monitoring in support of GCOS Switzerland.

Highlights of the National Climate Observing System

Switzerland has a long lasting tradition of climate observation. It hosts some of the oldest measurement series of ECVs including:

  • Phenological data on the chestnut bud burst in Geneva since 1808
  • Temperature and precipitation measurements starting more than 150 years ago
  • Glaciological data extending back to the end 19th century
  • The world’s longest ozone series starting in 1926
