Roeland Van Malderen (Royal Meteorological Institute of Belgium)28/05/2024, 16:10Tropospheric ozone (Tue 28 May)
After a first successful phase of the Tropospheric Ozone Assessment Report (TOAR), which e.g. provided the first global scale view of all available surface ozone observations, the most extensive evaluation of historical (pre 1975) ozone observations and the first intercomparison of satellite ozone products, TOAR is now nearly the end of its second phase (TOAR-II, 2020-2024). TOAR-II will...

The Ozone Essential Climate Variable has been an essential part of ESA’s Climate Change Initiative (CCI, https://climate.esa.int/en/projects/ozone). This initiative strives to develop, mature, generate, and sustain harmonised, consistent, and validated multi-decadal satellite ozone time series specifically for climate monitoring, climate modelling, and climate research applications.
We...

Chemistry climate models (CCMs) are constructed to encapsulate our understanding of important atmospheric processes affecting the chemical state of the atmosphere, subject to the fundamental constraint imposed by our computational capacity to produce results in a reasonable amount of time. These models are routinely used to provide simulations to inform science and policy, including going back...

Changes in economic activity and emission controls over the past several decades have led to substantial changes in anthropogenic emissions globally. Meanwhile, climate change has been a key factor in increasing the risk and extent of natural processes such as extreme wildfire events. Satellite measurements have been used to explore these changing global patterns. However, the attribution to...

Viktoria Sofieva (Finnish Meteorological Institute)28/05/2024, 17:20Tropospheric ozone (Tue 28 May)
In this work, we present the tropospheric ozone datasets, which are created using combination of total ozone column data from nadir instruments (OMI, GTO-ECV) with stratospheric ozone column dataset from several available limb-viewing instruments (MLS, OSIRIS, MIPAS, SCIAMACHY, OMPS-LP, GOMOS). These datasets are included in the Ozone_cci+ Phase 2.
In the presentation, we will present...

The Ozone Mapping and Profiler Suite (OMPS) comprises three complementary ozone sensors – Limb Profiler (LP), Nadir Profiler (NP) and Nadir Mapper (NM) - that scan the same region of the atmosphere within minutes to measure the global ozone distribution at high spatial and vertical resolution. The combination of limb and nadir instruments on the same platform enables the estimation of...

Andrea Orfanoz-Cheuquelaf (IUP. University of Bremen)28/05/2024, 18:10Tropospheric ozone (Tue 28 May)
Combining space-borne limb and nadir measurements in the UV-visible spectral range (limb-nadir matching, LNM) provides valuable information on tropospheric ozone. This study uses data from the SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY (SCIAMACHY) (2002-2012) and Ozone Mapping and Profiler Suite on board of Suomi National Polar-Orbiting Partnership (OMPS/NPP, since...

Elyse Pennington (NASA JPL)28/05/2024, 18:25Tropospheric ozone (Tue 28 May)
We present an analysis of ozone data products retrieved from multiple satellite observations. Specifically, we highlight data from the TRopospheric Ozone and its Precursors from Earth System Sounding (TROPESS) project which is a NASA effort that provides retrievals of atmospheric ozone utilizing radiances from a variety of different satellite instruments. The multispectral retrievals of ozone...

Klaus-Peter Heue (DLR)28/05/2024, 18:40Tropospheric ozone (Tue 28 May)
A tropospheric ozone Climate Data Record from 1995 until end 2023 has been generated within ESA’s Climate Change Initiative programme. The GOME-type Tropical Tropospheric Ozone Essential Climate Variable (GTTO-ECV) satellite data record combines data from GOME, SCIAMACHY, OMI, the three GOME-2 missions and TROPOMI. The retrieval is based on the Convective Cloud Differential technique, which...
