Methodology:

Microclimate data was recorded at Anchorage Island. Data was automatically collected and recorded on an hourly basis. 10 climatic variables were recorded: wind speed, wind direction, air temperature, photosynthetically active radiation (PAR), UVA, UVB, temperature at 4 different depths.

Data collection:

Two loggers were used. 15-Jan-2008 - 13-Feb-2019 Logger: Campbell CR1000 serial no. 8288. 31-Jan-2006 - 15-Jan-2008 Logger: Campbell CR10X, serial no. XE6531.

The same sensors have been used throughout monitoring.

Variables: wind speed, wind direction. Sensor: Young 05103. Sensor serial no.: 65997.

Variables: temperature (all depths). Sensor: Campbell 107. Sensor serial no.:12966/5, 07006/8, 05393/3, ?.

Variable: photosynthetically active radiation. Sensor: Skye SK215.

Variable: UVA. Sensor: Delta-T UV-AP. Sensor serial no.: AP-002.

Variable: UVB. Sensor: Skye SKU430. Sensor serial no.: 0705 29724.

Data quality:

Missing values are included where data was not recorded, or where values indicating malfunctioning equipment have been removed. No extensive quality control or verification has been undertaken.

Due to the harsh conditions in Coal Nunatak, data has not been recorded continually across the period. The exact locations of sensors within the soil does change over time due to environmental conditions, so depths recorded are a guide.
