The Climate Reanalysis Task Force (TF) is an initiative of NOAA’s MAPP Program to advance NOAA’s climate reanalysis capability focusing on research to address outstanding issues in atmospheric, ocean, and land reanalysis and develop a greater degree of integration among Earth system reanalysis components. The Task Force brings together MAPP-funded scientists from universities, research laboratories, and NOAA centers and labs. The TF will facilitate coordination and synergies among the various MAPP funded projects to optimize research outcomes. It is envisioned that MAPP Climate Reanalysis Task Force efforts will build upon state-of-the-art NOAA reanalysis and data assimilation systems and aim at significant improvements beyond current capabilities in preparation for the next generation of NOAA’s climate reanalysis running from the 20th century to present, and potentially extending back to the late 19th century as feasible. The Task Force will build on synergies between reanalysis efforts at NOAA and other national modeling centers; and will coordinate with other ongoing national and international reanalysis efforts.

Start date is September 1 2013 and duration of this group activity is 3 years.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
