DESCRIPTION:TEMPO is NASA’s first Earth Venture Instrument (EVI) and firs
 t host payload. It measures hourly daytime atmospheric pollution over Nort
 h America from Mexico City to the Canadian oil sands\, and from the Atlant
 ic to the Pacific\, at high spatiotemporal resolution (~10 km2 at boresigh
 t) from the geostationary (GEO) orbit. It uses UV/visible spectroscopy (29
 3-493 nm\, 538-741 nm) to measure O3 profiles including lower tropospheric
  O3 and columns of NO2\, H2CO\, SO2\, C2H2O2\, H2O\, BrO\, IO\, as well as
  clouds aerosols\, and UVB. TEMPO provides a tropospheric measurement suit
 e that includes the key elements of tropospheric air pollution chemistry a
 nd captures the inherent high variability in the diurnal cycle of emission
 s and chemistry. The TEMPO instrument was built by Ball in 2018. It was in
 tegrated into the host commercial communication satellite Intelsat 40e (IS
 -40e) by Maxar. IS-40e was successfully launched on April 7 by a SpaceX Fa
 lcon 9 rocket on to the GEO orbit at 91W. The TEMPO Instrument powered up 
 for the first time on orbit in early June to start its commissioning. Afte
 r a month of dry out and activation\, TEMPO first light of solar and earth
  measurements occurred on July 31-August 2. TEMPO commissioning continues 
 until early October. Nominal operation is expected to begin after the comm
 issioning phase and the post-launch acceptance review. Science data produc
 ts are archived and distributed at NASA’s ASDC and will be released to t
 he public in approximately April 2024. TEMPO is part of a geostationary co
 nstellation to measure air quality along with GEMS (launched in Feb. 2020)
  over Asia and Sentinel-4 (to launch in 2024) over Europe.
