Annual Mean Air Temperature at Rothamsted 1878-2019

Rothamsted has one of the longest running continuous sets of meteorological recordings in the world. The figure shows the annual mean air temperature at Rothamsted every year from 1878-2013. Also shown is the mean over each five-year period, 1878-1882, 1883-1887, etc. The red line shows the mean temperature, 1878-1987. Mean annual air temperature has fluctuated considerably between 1878-2013. However, when the variation in annual temperature is smoothed using five-year means, it is apparent that air...

Sarah Perryman &
This dataset consists of the relative frequencies of Cirsium arvense (Creeping thistle) of the Family Asteraceae recorded on Section 8 plots of the Broadbalk Wheat Experiment, 1991-2018. Section 8 has not received any herbicides in its history. The collective weed fauna, and frequency of each species such as C. arvense, differ in response to fertiliser treatments which vary with each plot (see Related Documents below).

UK aphid migration percentiles, covariates and model outputs from the Rothamsted Insect Survey's 12.2 m suction-trap network: 1965 to 2018

Yoann Bourhis, James Bell, Frank Vandenbosch & Alice Milne
This dataset contains a measure of aphid arrival, the day of 1% detection (D1D), i.e. the Julian day at which 1% of the yearly aphid abundance has been captured. It is measured for 14 aphid species across the UK, from 1965 to 2018, by the Rothamsted insect survey suction-trap network. It amounts to a total of 881 samples (i.e. trap x year combinations). For all those samples, a measure of 59 covariates as potential predictors...

Rothamsted long-term liming experiment crop yields 1962-1996

Margaret Glendining, Steve McGrath & Keith Goulding
The experiment tests the effects of different amounts of lime (and thus soil pH), P and K on the yields of a sequence of arable crops, on a silty clay loam soil at Rothamsted Experimental Farm, from 1962-1996. Mg, Mn and S were tested on split plots at different times. Target soil pH was 4.5, 5.5, 6.5 and 7.5. There is a parallel experiment at Woburn Experimental Farm. Since 1997 the experiment has been in...

Sarah Perryman, Tony Scott & Rothamsted Research The Electronic Rothamsted Archive
Rothamsted has one of the longest running continuous sets of daily meteorological recordings in the world. Temperature has been measured since 1878.

Variation in annual temperature is smoothed using an 11-year (132 month) moving average (red line, which removes solar variability and shorter-term...
