TanSat carries two instruments: the Carbon Dioxide Spectrometer and the Cloud and Aerosol Polarimetry Imager. The Carbon Dioxide Spectrometer (CDS), also called CarbonSpec, is a high-resolution gratingspectrometer which measures CO2absorption at 1.61 μm and 2.06 μm, and O2 absorption in reflected sunlight at 0.76 μm. The Cloud and Aerosol Polarimetry Imager (CAPI) is a wide-field, moderate-resolution, imaging spectrometer which works in concert with CDS by compensating for measurement errors caused by clouds and aerosols. It makes observations in ultraviolet (0.38 μm), visible (0.67 μm), and near infrared (0.87 μm, 1.375 μm, and 1.64 μm).[5]
Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). Crewed flights are underlined. Launch failures are marked with the † sign. Payloads deployed from other spacecraft are (enclosed in parentheses).
