Automatic Weather Station - Glensaugh

This area of the webiste is undergoing maintenance.
We are currently carrying out maintenance to our live feeds; the information currently shown is not live.

Image showing the Automatic Weather Station at Glensaugh
Information on the air temperature, wind speed, soil temperature and rainfall is captured live at the Environmental Monitoring Site at Glensaugh. Data recorded from sensors deployed at field sites is fed live to this website.

Meteorological data is captured  at the environmental  monitoring site at Glensaugh.  This data is part of a long term monitoring study, Environmental Change Network (ECN), which aims to identify environmental changes and to distinguish short-term fluctuations from long term trends. Many other variables such as atmospheric chemistry, soil solution chemistry, water chemistry, vegetation, and soil properties are routinely measured.

For more information and a full site description please visit the ECN website.

Readings from the last 7 days and what do they mean?

Air Temperature

Air temperature

Air temperature is strongly influenced by wind speed and direction. In general terms peak temperatures are recorded on sunny days with low wind-speed. When strong, northerly winds dominate temperatures fall away and may dip well below freezing. There are strong seasonal effects with warm summers and cooler winters.

Net Radiation

Net solar radiation

Net solar radiation is the balance between the incoming and outgoing radiation from the sun. Solar radiation can be reflected or absorbed. Generally light coloured surfaces, for example snow, are more reflective than darker surfaces such as soil or vegetation. Surfaces that absorb radiation may subsequently release it.

Net solar radiation at our sites will generally be high during the day and low at night and higher in summer (due to day length) than winter.

Rainfall

Rainfall

The quantity and duration of rainfall during wet periods directly impacts on soil moisture and humidity. Rainfall delivered as a result of heavy showers may not have time to soak into the ground and may run relatively quickly into water courses quickly raising the water levels. Lighter, more persistent rain is likely to soak into the ground, raise the soil moisture and take longer to reach surface waters.

Relative Humidity

Relative humidity

The higher the relative humidity value the more moisture is in the air. When it is raining, misty and foggy relative humidity is 100%.

Soil moisture

This data is considered along with soil temperature and rainfall as measurements that influence the degree of biological activity and chemical processes that take place in the soil. Dry soils, particularly peat, become prone to cracking and the soil structure can change due to wetting/drying cycles and freeze thaw cycles.

Soil temperature

This data is usually related to soil moisture as both measurements influence the degree of biological activity and chemical process that take place in the soil. When soils are warmed, activity increases influencing decomposition rates. Root growth is generally faster in warmed soil.

Wind Rose

Wind direction

Northerly winds bring cooler air from the arctic regions and there is usually a corresponding drop in air temperature. The predominant air flow is from the West carrying moist but relatively mild air from the Atlantic.

Wind Speed

Wind speed

As the strength of the wind increases there will be an impact on plants, animals, property and people. Strong winds, particularly Northerly winds, will reduce the air temperature and there will be more significant wind chill making it feel cold.

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
