The Atmospheric Chemistry Experiment (ACE) is comprised of a Fourier transform spectrometer (ACE-FTS) operating in the infrared with broad spectral coverage (750 – 4400 cm-1) and high resolution (0.02 cm-1), a UV-Visible-NIR spectrophotometer (ACE-MAESTRO, Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) with wavelength coverage 280 – 1030 nm and...
The MATS (Mesospheric Aerosol/Airglow Tomography and Spectroscopy) satellite was finally launched on 4 November 2022 aboard an Electron rocket from New Zealand. It entered a 585 km sun-synchronous orbit with an LTAN of 17:45. Already a few days after launch first light was seen by the instrument confirming its functionality and ability to collect the planned data.
MATS images the...
The Changing-Atmosphere Infra-Red Tomography Explorer (CAIRT) is currently in Phase 0 as one of four candidates for ESA’s Earth Explorer 11. As a Fourier transform infrared limb imager, CAIRT will observe simultaneously from the middle troposphere to the lower thermosphere at high spectral resolution in 3D with unprecedented horizontal and vertical resolution. With this, CAIRT will provide...
The Limb Profiler (LP) is a part of the Ozone Mapping and Profiler Suite on the Suomi NPP satellite. We present a new version of the ozone profile product processed at NASA Goddard Space Flight Center (GSFC). In this study we summarize changes implemented in version 2.6 including changes in both Level 1 and Level 2 algorithms. In this presentation we focus on algorithmic Level 2 changes. The...
Stratospheric aerosols play key roles in the chemistry and radiation balance of the atmosphere and are a key input parameter for global chemistry and climate models. The degree to which aerosols impact chemistry and radiation balance depends primarily on the relative abundance of different sized particles within the sample volume, often referred to as the particle size distribution (PSD). If...
