First Global Measurement of Cloud Ice in Upper Troposphere
Cloud ice measurement will improve global circulation models used for weather and climate forecasts.
The measurements will also help quantify the upper tropospheric hydrological cycle, including water vapor feedbacks on climate change.
Measurement of CO in Upper Troposphere
CO is a signature of pollution and can be transported a long way from its source. Not surprisingly, that transport can be vertical as well as horizontal. These images show how CO detected in the lower stratosphere can tell us something about where convection is occurring.
Continuous measurement of HCl in stratosphere
The continuous measurement of HCl in the stratosphere shows the rapid recovery of this major chlorine reservoir after polar ozone loss, and continues the long-term measurements from UARS HALOE. Monitoring HCl tells us about ozone loss processes and the recovery of the ozone layer.
First Measurement of OH in the Middle Stratosphere
The MLS measurements of OH and HO2 have provided the first tests of global stratospheric hydrogen chemistry and resolved the disagreement between model estimates of OH and earlier observations - these data suggest earlier observations are suspect.
