TITLE: "Attributing observed changes in surface air temperature and rainfall over India"

SPEAKER: KRISHNA ACHUTARAO, CENTER FOR ATMOSPHERIC SCIENCES, IIT DELHI

TIME AND DATE: 3:30 PM, MONDAY, 4 FEBRUARY 2019

VENUE: CAOS SEMINAR HALL

ABSTRACT

Observed trends in temperature and rainfall over India are analyzed from a detection and attribution (D&A) perspective. Increasing temperatures over India since the middle of the 20th Century over various homogeneous zones of India were analyzed in a recent study by Dileep kumar et al., (2018) who concluded that observed increases can be attributed to forcings from greenhouse gases that have been offset by other anthropogenic factors (including anthropogenic aerosols and land use land cover change). However, the linear regression based D&A method cannot disaggregate the role of anthropogenic aerosols alone since the response to different forcings is not always linearly additive.
