This dataset represents the mean monthly rainfall recorded at Rothamsted from October 1986 - September 2018 and is derived from continuous daily records measured at the site.
This dataset was compiled for the publication J. Macholdt, H.-P. Piepho, B. Honermeier, S. Perryman, A. Macdonald and P. Poulton.

Daily rainfall is measured as the total (mm) over the 24-hour period 0900 to 0900 GMT. It includes all precipitation - snow, rain, mist and fog. Rainfall was first recorded at Rothamsted in March 1853, using a copper funnel rain gauge (5 inch / 12.7 cm diameter) and measured using a graduated cylinder. Since 2004 it has been measured using an electronic tipping bucket rain gauge (10 inch / 25.4cm diameter), ARG100, calibrated to tip at 0.2mm (which has since become the minimum amount of rain that can be recorded). The rain gauge is placed within a 30cm deep 1.5m radius turf wall, retained by brick, to reduce wind eddies that may potentially blow rain out of the gauges. Data were collected daily manually until 2004 and since then by Automatic Weather Station using a standard protocol. There are differences in the capture rate between the two gauges, see Rainfall for further information.

The monthly summary data contained in this spreadsheet are derived from daily data measured at Rothamsted Meteorological Station, Harpenden. Total monthly data is determined from daily data using Genstat 19th Edition. Verification includes checks for instrument errors, for missing data and outliers. Missing values are acquired form the UK Met Office Station on site. The original raw daily data is available, after registering, from the e-RA database.
