Multi-Angle Imager for Aerosols (MAIA)

MAIA was selected in 2016, with launch in 2022 (to be confirmed) and a baseline mission of 3 years.

MAIA’s science objective is to study the effects of various types of PM on:ü Acute illness and premature

deathü Adverse birth outcomesü Chronic disease

The MAIA investigation concept

71/4/2019 HAQAST5

MAIA instrument o Calibrated,

georectified image data for retrieval of column-integratedAOD, fractional AOD, particle size.

Surface PM monitorso Used to calibrate the

aerosol-PM relationships.

o MAIA will use existing PM networks and deploy additional speciation monitors.

WRF-Chemo Constrains aerosol

vertical distribution.

o Assists spatial/temporal gap-filling.

Health recordso Obtained from Vital

Statistics, hospitals, HMOs, administrative records, cohorts.

o Used to associate PM exposure with health effects.
