Bro (Column/Profile)
Measurement Instruments
Measurement Definition: BrO = Bromine monoxide. Requested from surface to TOA (layers: LT, HT, LS, HS&M) - Physical unit: [ ppm ] - Accuracy unit: [ % ].
| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| EMI-2 | Operational | Ozone profile and total-column or gross profile of other species. Tracked species: BrO, ClO H2O, HCHO, NO, NO2, O3, SO2 and aerosol | n/a |  |
| MLS (EOS-Aura) | Operational | Measures lower stratospheric temperature and concentration of H2O, O3, ClO, HCl, OH, HNO3, N2O and SO2. | Limb-scanning MW spectrometer | |
| NACHOS Hyperspectral Imager | Operational | | n/a | |
| OSIRIS | Operational | Detects aerosol layers and abundance of species such as O3, NO2, OClO, BrO and NO. Consists of spectrograph and IR imager. | n/a | |
| TROPOMI | Operational | Supporting atmospheric composition and air quality monitoring services. | n/a | |
| ALTIUS Instrument | Being developed | A high-resolution 2D imager that observes ozone from side-on, at Earth's limb or atmospheric boundary. This limb-sounding technique allows ozone to be viewed at different altitudes, thereby providing vertical profiles of different ozone concentrations. The instrument uses three independent spectral imagers that operate in the ultraviolet, visible and near-infrared, achieving global coverage in a three-day revisit cycle. | n/a | |
| UVN (Sentinel-4) | Being developed | Supporting atmospheric composition and air quality monitoring services. | n/a | |
| UVNS (Sentinel-5) | Being developed | Supporting atmospheric composition and air quality monitoring services. Measurements of atmospheric trace gases, primarily O3, NO2, SO2, HCHO, CH4, CO, CHOCHO as well as Aerosols and UV Index. | n/a | |
