Menglin Jin, Lorraine Remer

• 6-year daily averaged aerosol optical thickness
  (AOT) from AERONET show
• significant differences between Beijing and New
  York City, seasonal variation of urban aerosol

Regional climate model (MM5) simulates surface
temperature reduction due to urban aerosol by
-2ºC during the day.
