Summary Products

• Ammonia (NH3) - Vertically integrated total column

• Carbon monoxide (CO) - Column-averaged dry air mixing ratio from the surface to the Top of the Atmosphere (TOA), also known as XCO

• Methane (CH4) - Column-averaged dry air mixing ratio for the partial column between 826 hPa and the Top of the Atmosphere (TOA), also known as free tropospheric XCH4

• Ozone (O3) - Vertically integrated total column and tropospheric column

• Peroxyacetyl Nitrate (PAN) - Column-averaged dry air mixing ratio for the partial column between 826 hPa and 215 hPa, also known as free tropospheric XPAN

• Semi-heavy water vapor (HDO / Delta-D) - Partial column between 850 and 250 hPa, expressed in parts per thousand relative to the deuterium content of ocean waters (also known as Delta-D)
