 The IPA has a Memorandum of Understanding with the Climate and Cryosphere (CliC) programme of the World Climate Research Programme (WCRP).The main areas of cooperation are on the roles of permafrost on water and carbon balances, and data assimilation and modelling.Beginning in 1995 the IPA and the International Geographical Union (IGU) developed an Agreement of Cooperation, thus making IPA an affiliate of the IGU.
