Marcia Baker is a retired professor known for her research on cloud physics which informs global climate models and defines the processes leading to the formation of lightning from clouds.
Baker graduated in 1955 from Urbana High School in Illinois.
She retired in 2004[5] Baker's research on cloud physics informs climate change models.
[6] Her early research examined how atmospheric particles absorb energy[7] and the formation of droplets within cumulus clouds.
She has also used a combination of modeling and satellite observations to establish the processes that lead to the formation of lightning.
