Hydrogen Chloride from new Microwave Limb Sounder on Aura (WMS)
Hydrogen chloride (HCl) in the atmosphere as measured by the Microwave Limb Sounder (MLS) instrument on NASA's Aura satellite. MLS can simultaneously measure several trace gases and ozone-destroying chemicals in the upper troposphere and photosphere. In this series of animations we present chlorine monoxide (ClO), hydrogen chloride (HCl), nitric acid (HNO3), ozone (O3), water vapor (H2O) and temperature measurements. These are 'first light' data taken when the MLS was operated for the first time. Ozone-destroying chlorine (Cl) atoms are neutralized when they bond with hydrogen (H) to form HCl.
This animation shows hydrogen chloride (HCl) in the atmosphere from August 13 through October 15, 2004. Red represents high concentrations; blue represents low concentrations. The spatial resolution is low: each pixel covers an area of 5 degrees longitude by 2 degrees latitude, so the entire world (except for 1 degree at each pole) is covered by the 72x89 pixel images.
This product is available through our Web Map Service.
Color scale for hydrogen chloride concentration. Values shown range from 0 to 2.5 ppbv (parts per billion by volume).
