||NASA Ozone Study May Benefit Air Standards (Science Daily article)|
A new NASA-led study uses TES data to find that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters. [Geophysical Research Letters Editors' Highlight]
||Comparison with observations shows cloud simulations improving |
Evaluation of cloud and water vapor simulations in CMIP5 climate models using NASA "A-Train" satellite observations [Journal of Geophysical Research - Atmospheres Editors' Highlight]
||ENSO in Lower Atmospheric Ozone|
The response of tropospheric to lower stratospheric ozone to El Niño Southern Oscillation (ENSO) is derived using measurements from the Microwave Limb Sounder (MLS) and Tropospheric Emission Spectrometer (TES).
|| Signature of the Solar Rotational Cycle in Mesospheric Hydroxide and Water|
The AURA Microwave Limb Sounder (MLS) data reveal a strong OH and H2O response to the 27-day solar irradiance variability.
|| Satellite measurements of Sulfur Dioxide|
Aura/OMI data is used in conjunction with data from a dual ozone sonde payload to observe sulfer dioxide.
|| TES First Measurements of PAN |
Quantifying Peroxy Acetyl Nitrate (PAN) concentrations in pollution plumes is important for understanding the potential impact of the long-range transport of air pollution.
||Measurements of Aerosols Above Clouds |
The Aura project has developed a method to measure the optical depth of absorbing smoke and dust aerosols located above clouds using satellite observations.
||Observations of Nabro eruption |
SO2 retrievals on the Nabro's volcanic plume using hyperspectral UV measurements made by Ozone Monitoring Instrument (OMI) on June 13
||A-train data for Merapi volcanic cloud |
Gaseous and aerosol clouds from major explosive eruption of Indonesia's Merapi volcano were measured by multiple A-train sensors
||Destruction of Mesospheric Arctic Ozone Caused by Solar Protons |
Microwave Limb Sounder (MLS) observations quantify the changes in the hydroxyl radical (OH), hydrogen dioxide (HO2), and ozone due to Solar Proton Events (SPE)
||Enhancements in NO2 and SO2 over the Canadian oil sands |
Data from the Ozone Monitoring Instrument (OMI) show distinct enhancements in nitrogen dioxide (NO2) and sulfur dioxide (SO2 ) over a region of surface mining in the Canadian oil sands.
||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?
Aura data are delivered to users through the NASA Data and Information Services Center (DISC).
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.
