Post-deforestation Amazonian climate: Anglo-Brazilian research to improve prediction

Abstract This paper reviews the experimental activity and primary results of the Amazon Region Micrometeorology Experiment (ARME), and the subsequent impact of these data in improving the prediction of post-deforestation Amazonian climate using general circulation models. It previews the new 5 year programme of collaborative Anglo-Brazilian research which will extend these studies by providing calibration of the land-atmosphere interaction for cleared forest areas, and measurements of the comparative near-surface climatology for large clearings and adjacent areas of undisturbed natural forest. Finally it overviews preliminary plans for a major international study in Amazonia under the World Climate Research Programme and the International Geosphere Biosphere Programme.
