We are using three Skye Instrument (the company ceased trading in 2025) automated weather station (AWS), measuring hourly air temperature (Tair), soil temperatures (Tsoil), air humidity (RH), barometric air pressure, photosynthetically active radiation (PAR), global radiation and rainfall.

ABOVE: Examples of daily climate data from the three AWS stations at Nidderdale, Mossdale and Whitendale; for monthly data (available as averages) for soil and air temperature and daily sums of rainfall and PAR (photosynthetically active radiation - light) click on the Table links below. NA denotes missing data (faulty sensor).

BELOW: Monthly average climate data from the three AWS stations at Nidderdale, Mossdale and Whitendale (monthly data are available (click on the Table links above) as averages for soil and air temperature and sums of rainfall and PAR (photosynthetically active radiation - light) together with the annual averages/totals (tables underneath the graphs).

Top left: Summary of mean total annual light (photosynthetically active radiation [PAR]; yellow) and total rainfall amounts (blue) averaged across the three sites. Clearly visible are a downward trend (about 20 mm per year) for rainfall with two very dry years (2013, 2018) and two very wet years (2012 & 2015) and an upward trend for PAR (about 75 mol m-2 per year) with a very bright year in 2025. The regression equations are shown with the corresponding R2.

Top right: Mean air (red dots) and soil (brown dots) temperatures (T) averaged across all three sites over the monitoring time showing a clear upward trend (rising for T air and T soil by about 0.86°C and 0.6°C per year, respectively) over time with a noticeable warm peak in 2014. The regression equations are also shown with the corresponding R2.
