What are the essential climate variables?

What are essential climate variables?

An ECV is a physical, chemical or biological variable or a group of linked variables that critically contributes to the characterization of Earth’ s climate.

How many essential climate variables are there?

The Global Climate Observing System (GCOS) currently specifies 54 ECVs, of which about 60 per cent can be addressed by satellite data.

What are the 8 climate variables?

Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, which includes the ocean, land, and ice on Earth.

What do the essential climate variables cover?

Essential Climate Variables (ECVs) are derived in part from Climate Data Records, and address the following terrestrial categories: River Discharge; Water Use; Groundwater; Lake and Reservoir Levels and Volumes; Snow Cover; Glaciers and Ice Caps; Permafrost; Land Surface Albedo; Land Cover; Absorbed Photosynthetically …

What are the seven climate variables?

These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds.

What are the weather variables?

Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

Climate graphs show average rainfall and temperatures typically experienced in a particular location.

What is climate variability?

Climate variability refers to the climatic parameter of a region varying from its long-term mean. Every year in a specific time period, the climate of a location is different. Some years have below average rainfall, some have average or above average rainfall.
