Table 1 Percent agreement between human observations of rainfall changes and instrument-based precipitation indices for the globe

From: Using human observations with instrument-based metrics to understand changing rainfall patterns

  1. Human observations were compared with the closest available climate observation, and we identified a match if the sign of the climate trend was consistent with the sign of the human observation. Percent agreement (%) and the number of human observations within 250 km of instrumental observations for each measurement index/data source are shown (in parentheses). High, medium and low agreement is colour coded for ease of interpretation: dark grey (>65% match), light grey (between 65% and 35%), and white (<35%.). The database’s total number of human observations for Drought, Extreme Rainfall and General Rainfall are also shown (N). Observed instrument-based trends are from 1955 to 2005. Values in bold indicate measurement indices best corresponding with human observation types (i.e., indices of lack of rainfall and relative dryness with observations of increased drought). GPCC Global Precipitation Climatology Centre, GHCNDEX gridded temperature and precipitation climate extremes indices from the Global Historical Climatology Network (GHCN) dataset, HadEX3 dataset of gridded station-based climate extremes indices. Human observations are provided as source data.
