The project "Angra" has been completed successfully (March 2014)
5-daily surface station weather observations from the city of Angra on the Azores Islands (Portugal) for the period 1902-1905 have been digitised. The total number of digitised values (pressure, temperature, dew point difference, minimum and maximum temperature, vapour pressure, relative humidity, precipitation amount, wind direction and velocity, cloud amount and state of the sea, evaporation and ozone) is 128,822. The historical weather data from the Azores Islands are particularly valuable since the islands are located at the southern node of the most important climatic variability mode in the North Atlantic-European region, the so-called North Atlantic Oscillation (NAO), and there are not much other historical data available from the larger region.
More than 1 million values digitized (January 2014)
As of January 2014, Data-Rescue-At-Home has digitized almost 1.3 mio values. We thank all contributors for their time - the data will contribute to a better view of historical world weather and climate.

Timeline

The following table shows how many values were digitized by our users. To solve a single number from a picture at least three solutions from different useres are needed.
