AB: Tropospheric pollution measurements from space now include ozone (O₃), volatile organic compounds (VOCs, using tropospheric formaldehyde - HCHO - as the primary proxy for VOCs), and odd nitrogen (NO_x, using tropospheric nitrogen dioxide - NO₂ - as the proxy for NO_x), glyoxal (CHOCHO, an alternate proxy for VOCs, currently being developed), sulfur dioxide (SO₂), carbon monoxide (CO), methane (CH₄), and water (H₂O). Satellite measurements of these gases have been robustly demonstrated and are now routinely made. Data analysis algorithms for analyzing these gases are mature. Geostationary measurements are the logical next step in pollution monitoring from space. This presentation discusses the capabilities and limitations for geostationary monitoring of pollution, and presents requirements for the instrument design and observations. Ultraviolet/visible measurement requirements and implementation for O₃, NO₂, HCHO, CHOCHO, and SO₂ are presented in detail. Infrared measurements approaches for CO, CH₄, and O₃ are discussed and some novel approaches for their measurement presented.
