r than normal monsoon season usually preceding peak El Nio conditions and a wetter than normal monsoon season preceding peak La Nia conditions. However, sea surface temperatures (SST) in the Pacific, which serve as an indicator of the phase of the ENSO cycle, are not the only factors affecting Indian monsoon patterns. Building on their recent discovery that atmospheric teleconnections between the tropical Atlantic Ocean and the Indian basin contributed to the weakening of the ENSO-monsoon link during the 1980s and 1990s, Kucharski et al. investigate the role of south equatorial Atlantic SSTs in forcing the volume and pattern of Indian monsoon rainfall. Using two observational data sets and two ensembles of models, the authors show that characteristics of Indian monsoon rainfall are significantly correlated with south equatorial Atlantic SSTs. The authors expect that their results might help with monsoon forecast efforts.

7. Improving measures of wildfire smoke heights from space

The elevation at which wildfire smoke is injected into the atmosphere has a strong influence on how the smoke is dispersed and is a key input into aerosol transport models. Currently, spaceborne lidar studies can constrain the height of smoke plumes with great precision, but horizontal sampling is very poor on large scales. Spaceborne stereo i
