Overview of the Rothamsted Weather Station

• The daily data in the e-RA database 'e-RAdata' Daily data is provided to 1 d.p. and rounded up. There are occasionally missing values (due to instrumentation issues) which over many years are insignificant but may skew mean data. . These missing data are available from the Met Office weather station which is also in the same location on the Rothamsted site. These data can be obtained on request from the e-RA Curators. A daily diary documenting visual observations of weather was kept from 1853-1959 and these historical written records are also available from our database.
  
  The summary data in the downloadable summary 'Datasets' are derived from both Rothamsted weather station daily data in the e-RA database as well as data from the Met Office station also onsite alongside it, to provide complete records.

• The Met Office weather station equipment are situated immediately alongside the Rothamsted Research weather station. There can be minor variation between the two sets of data due to differing equipment and slight variation in the locations of the equipment. The Rothamsted Research weather station data are raw data, with missing values when there is an issue with equipment, whereas the met office data has been quality controlled and adjusted where necessary (using triangulation with nearby weather stations to infill missing data).
