World Weather Records (WWR) Clearinghouse

World Weather Records (WWR) is an archived publication and digital dataset of meteorological data from locations around the world. WWR was initially launched in 1927 as a publication. Data includes monthly mean values of pressure, temperature, precipitation, relative humidity, and where available, station metadata notes that document observation practices and station configurations. 

11th Series (2011–2016)

Series 11 continues the record of monthly mean values of station pressure, sea-level pressure, temperature, and monthly total precipitation for stations listed in previous volumes. In addition to these parameters, mean monthly maximum and minimum temperatures and relative humidity have been collected for many stations and are archived in digital files by NCEI. New stations have also been included.
