Surface Wind Speed and Direction
Surface pressure is a fundamental meteorological variable controlling weather systems and providing information on the intensity of weather systems, including tropical cyclones. -
Aerosols (Atmosphere - Atmospheric Composition)
Atmospheric aerosols are minor constituents of the atmosphere by mass, but a critical component in terms of impacts on the climate and especially climate changes. Aerosols... -
Carbon Dioxide, Methane & Other Greenhouse Gases (Atmosphere - Atmospheric Co...
The atmospheric abundance of carbon dioxide (CO2), the dominant human-produced greenhouse gas, has increased by about 50% since pre-industrial times due to the proliferation of... -
Upper-Air Water Vapour
Water vapour is the predominant gaseous source of infrared opacity in the atmosphere, accounting for about 60% of the natural greenhouse effect for clear skies. Water vapour... -
Upper-Air Wind Speed and Direction
Wind is one of the fundamental state variables for understanding and predicting the behaviour of the atmosphere. It is basic to the working of the climate system through... -
GroundWater
It is estimated that groundwater accounts for about 30% of the world’s total freshwater resources, and it is by far the largest available reservoir of liquid freshwater.... -
Subsurface Temperature
Subsurface temperature is a fundamental variable that is required to monitor variability and change in the physical environment of the ocean, energy flows, climate patterns and... -
Lakes
Information on changes in lake level and area is required on a monthly basis for climate assessment purposes. Approximately 95% of the volume of water held globally in... -
Surface Water Vapour
The humidity of air near the surface of the Earth affects the comfort and health of humans, livestock and wildlife, the swarming behaviour of insects and the occurrence of plant... -
Sea Level
Sea Level is one of the primary indicators of global climate change. Change in the global mean sea level provides a measure of the net change in ocean mass due to melting of... -
Upper-Air Temperature
Temperature is one of the fundamental state variables for understanding and predicting the behaviour of the atmosphere. It is basic to the energy budget of the climate system as... -
Surface Temperature
Surface air temperature has profound and widespread impacts on both natural systems and on human lives and activities. It affects health, agriculture, energy demand and much... -
Permafrost
The properties of frozen ground react sensitively to climate and environmental changes in high-latitude and high-altitude regions. This includes the temperature distribution in... -
Ice Sheets and Ice Shelves
The understanding of the timescale of ice sheet response to climate change has changed dramatically over the last decade. Rapid changes in ice-sheet mass have surely contributed... -
Above-Ground Biomass (Land - Biosphere)
Vegetation biomass is a crucial ecological variable for understanding the evolution and potential future changes of the climate system. Photosynthesis withdraws CO2 from the... -
Plankton
Plankton are at the base of the marine food web and generally not fished by humans. Changes in the plankton will have impacts on the rest of the marine ecosystem including on... -
Earth Radiation Budget
The Earth Radiation Budget (at the top of the atmosphere) describes the overall balance between the incoming energy from the sun and the outgoing thermal (longwave) and... -
Lightning
Lightning is one of the most dramatic weather phenomena, causing many fatalities as well as substantial loss and damage for example by forest fires, damage to electrical... -
Snow
Snow refers to forms of ice crystals that precipitate from the atmosphere (usually from clouds) and undergo changes on the Earth's surface. Snow cover on the ground plays a... -
Ozone
Ozone (O3) is a naturally occurring trace gas in the stratosphere that inhibits harmful UV radiation from reaching Earth’s surface. Ozone in the troposphere is a pollutant,...
