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...

Extracted features from opto-acoustic audio recordings of aphids and beetles

Kirsty Hassall, Alex Dye & James Bell
Opto-acoustic recorders have been utilised to record the flight of weak-flying insects including aphids (Hemiptera: Aphididae) and beetles (Coleoptera). These data include 52 extracted features from 4928 audio recordings collected in 2019 and 2020 of 8 distinct species.

Smart Armyworm Surveillance: Project Technical Report

Aislinn Pearson, James Bell, S. Subramanian & K. Ouma
This project was designed to test three different technologies for monitoring the fall armyworm, a highly migratory moth pest of maize in Kenya. This insect is invasive and is estimated to have caused between US$200 and US$600 million dollars’ worth of crop damage in Africa since it was first observed in western Africa in 2016. The three technologies we piloted were entomological radar, digital pheromone traps and an image identification app. The hypothesis we set...

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 Insect Survey, Moth and Aphid catch abundance data

James Bell, Dan Blumgart & Chris Shortall
This dataset contains Moth and Aphid catch abundance data from the Rothamsted Insect Survey light-trap and suction trap networks. The dataset is a supplement to Bell et al (2020) (https://doi.org/10.1111/icad.12412) and can be used to reproduce the R analyses presented.

BKYIELD: Broadbalk wheat grain and straw yields 1844-1925

Wheat grain and straw yields have been recorded every year since the experiment began, with the first harvest in 1844 (the crop was sown in autumn 1843). Dried grain and straw samples have also been kept for chemical analysis since 1844; these are preserved in the Rothamsted Sample Archive.

Annual Mean Air Temperature Anomaly at Rothamsted 1878-2019

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. The figure above shows the temperature anomaly in annual mean air temperature (black circles), for years 1878 to 2019, relative to the 1878 to 1920 long-term average, which represents the pre-industrial era. Variation in annual temperature is smoothed using an 11-year (132 month) moving average (red line, which removes solar variability and shorter-term...
