Latest Science Features

	Global Characteristics of the Double Tropopause The global pattern of the double tropopause is revealed using the HIRDLS high vertical resolution profiles. Composition and structure near the tropopause are important for the Earth radiative balance and quantifying transport of ozone and other stratospheric species into the troposphere.
	BrO enhancements over the North Pole OMI, with its wide swath, is the only instrument that can detect Bromine Monoxide (BrO) at the pole on every orbit. Here, stratospheric BrO has been carefully separated from the total column to produce estimates of the tropospheric BrO column.
	Hydroxyl radical (OH) response to the 11-year solar cycle OH data from the Microwave Limb Sounder (MLS) on Aura and a ground-based FTUVS suggest a response of the OH column to the solar cycle that is significantly larger than model results using established solar forcing.
	What caused unusually low Arctic O₃ in Spring 2011? The Microwave Limb Sounder (MLS) on NASA's Aura shows weaker than usual ozone transport and strong photochemical loss
	Direct observations of megacity emissions and lifetimes of nitrogen oxides using OMI Emission inventories in megacities are uncertain, particularly in developing countries. Can we use OMI to better quantify these emissions without a model?

Where To Find Aura Data

Aura data are delivered to users through the NASA Data and Information Services Center (DISC).

For HIRDLS, MLS and OMI, the data are held at the Goddard Earth Science DISC. Data can also be accessed through the Giovanni system.

For TES, the data are held at the NASA Langley Atmospheric Sciences Data Center. The Aura instrument validation data are held at the Aura Validation Data Center at Goddard Space Flight Center.

Aura data users should download the data user guides available at the instrument web sites, and should contact the science teams for additional questions about the data.
