Press Release: IEDRO Contributes Critical Data to 20th Century Reanalysis Project

Deale, Maryland – On January 25, 2011, a review article of the Twentieth Century Reanalysis Project was published in the Quarterly Journal of the Royal Meteorological Society. This article reviewed the work of the Twentieth Century Reanalysis Project, which aims to create a comprehensive dataset of global atmospheric circulation from 1871 to the present.

The Project appears to be producing promising results. Using the dataset, scientists have been able to generate a global weather prediction model that offers an estimate of the state of the atmosphere every six hours and provides an uncertainty estimate of that analysis. Comparing the dataset’s forecasts to independent radiosonde data for the same period suggests that the estimates are of good quality. This dataset will be useful for climate research scientists from which they will conduct diagnostic studies and for validating current and future models.

Climate data that IEDRO rescued from Chile provided the backbone of the Twentieth Century Reanalysis Project’s Southern Hemisphere analysis. IEDRO is proud to have provided valuable data for the 20 th Century Reanalysis Project and remains confident that its ongoing work in collecting climate data will lead to better climate forecasts and thus save lives.

The International Environmental Data Rescue Organization (IEDRO) is a US-based, 501(c)(3) nonprofit organization that rescues and digitizes historic weather observations throughout the world. Our efforts are supported and endorsed by the National Oceanic and Atmospheric Administration, the World Meteorological Organization and other international groups concerned with the preservation and digitization of this valuable data.

Only with accurate information about the past can we make the necessary preparations for the future. With historic weather data we can conduct climate change and global warming research, forecast the spread of disease, and improve flood forecasting. Rescuing historic environmental data can do more to prevent human suffering and death than any other endeavor in the 21st century.
