Global Cloud Fraction (CF). Clouds play a crucial role in the Earth's climate system and have significant effects on trace gas retrievals. The radiometric cloud fraction is retrieved from the UV using the OCRA algorithm. Daily observations are binned onto a regular latitude-longitude grid.
The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers.
The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4).
Within the INPULS project, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.

Das Projekt "Mapping Carbon Pricing Initiatives - developments and prospects" wird/wurde gefördert durch: World Bank. Es wird/wurde ausgeführt durch: Ecofys Germany GmbH.The uncertainty surrounding the future of existing carbon markets in recent years has prevented valuable resources from being channeled to low-carbon investments, particularly from the private sector. Additionally, the prospect of a coordinated international approach to carbon pricing will remain uncertain for several years. However, the report reveals, that regional, national and sub-national carbon pricing initiatives are proliferating. Despite weak international carbon markets, both developed and developing countries are mainstreaming carbon pricing initiatives in national climate change and development strategies. This report prepared by the World Bank together with Ecofys, replaces the State and Trends of the Carbon Market series. Unlike in previous years, the report does not provide a quantitative, transaction-based analysis of the international carbon market as current market conditions invalidate any attempt and interest to undertake such analysis. The development of national and sub-national carbon pricing initiatives in an increasing number of countries calls for a different focus. This report maps existing and emerging carbon pricing initiatives around the world, hence its new title. It analyses common considerations across the initiatives, such as setting the appropriate ambition level, implementing price stabilization mechanisms, using offsets, and taking concrete moves towards linking schemes together. Feel free to watch below webcast by Alyssa Gilbert to familiarise yourself with the main outcomes of the study.

Das Projekt "Forest management in the Earth system" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Max-Planck-Institut für Meteorologie.The majority of the worlds forests has undergone some form of management, such as clear-cut or thinning. This management has direct relevance for global climate: Studies estimate that forest management emissions add a third to those from deforestation, while enhanced productivity in managed forests increases the capacity of the terrestrial biosphere to act as a sink for carbon dioxide emissions. However, uncertainties in the assessment of these fluxes are large. Moreover, forests influence climate also by altering the energy and water balance of the land surface. In many regions of historical deforestation, such biogeophysical effects have substantially counteracted warming due to carbon dioxide emissions. However, the effect of management on biogeophysical effects is largely unknown beyond local case studies. While the effects of climate on forest productivity is well established in forestry models, the effects of forest management on climate is less understood. Closing this feedback cycle is crucial to understand the driving forces behind past climate changes to be able to predict future climate responses and thus the required effort to adapt to it or avert it. To investigate the role of forest management in the climate system I propose to integrate a forest management module into a comprehensive Earth system model. The resulting model will be able to simultaneously address both directions of the interactions between climate and the managed land surface. My proposed work includes model development and implementation for key forest management processes, determining the growth and stock of living biomass, soil carbon cycle, and biophysical land surface properties. With this unique tool I will be able to improve estimates of terrestrial carbon source and sink terms and to assess the susceptibility of past and future climate to combined carbon cycle and biophysical effects of forest management. Furthermore, representing feedbacks between forest management and climate in a global climate model could advance efforts to combat climate change. Changes in forest management are inevitable to adapt to future climate change. In this process, is it possible to identify win-win strategies for which local management changes do not only help adaptation, but at the same time mitigate global warming by presenting favorable effects on climate? The proposed work opens a range of long-term research paths, with the aim of strengthening the climate perspective in the economic considerations of forest management and helping to improve local decisionmaking with respect to adaptation and mitigation.
Das Projekt "Schwerpunktprogramm (SPP) 1294: Bereich Infrastruktur - Atmospheric and Earth system research with the 'High Altitude and Long Range Research Aircraft' (HALO), CoMet (Carbon Dioxide and Methane) Mission" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR), Institut für Physik der Atmosphäre, Abteilung Lidar.Confronting Climate Change is one of the paramount societal challenges of our time. The main cause for global warming is the increase of anthropogenic greenhouse gases in the Earth's atmosphere. Together, carbon dioxide and methane, being the two most important greenhouse gases, globally contribute to about 81% of the anthropogenic radiative forcing. However, there are still significant deficits in the knowledge about the budgets of these two major greenhouse gases such that the ability to accurately predict our future climate remains substantially compromised. Different feedback mechanisms which are insufficiently understood have significant impact on the quality of climate projections. In order to accurately predict future climate of our planet and support observing emission targets in the framework of international agreements, the investigation of sources and sinks of the greenhouse gases and their feedback mechanisms is indispensable. In the past years, inverse modelling has emerged as a key method for obtaining quantitative information on the sources and sinks of the greenhouse gases. However, this technique requires the availability of sufficient amounts of precise and independent data on various spatial scales. Therefore, observing the atmospheric concentrations of the greenhouse gases is of significant importance for this purpose. In contrast to point measurements, airborne instruments are able to provide regional-scale data of greenhouse gases which are urgently required, though currently lacking. Providing such data from remote sensing instruments supported by the best currently available in-situ sensors, and additionally comparing the results of the greenhouse gas columns retrieved from aircraft to the network of ground-based stations is the mission goal of the HALO CoMet campaign. The overarching objective of HALO CoMet is to improve our understanding and to better quantify the carbon dioxide and methane cycles. Through analysing the CoMet data, scientists will accumulate new knowledge on the global distribution and temporal variation of the greenhouse gases. These findings will help to better understand the global carbon cycle and its influence on climate. These new findings will be utilized for predicting future climate change and assessing its impact. Within the frame of CoMet and due to the operational possibilities we will concentrate on small to sub-continental scales. This does not only allow to identify local emission sources of greenhouse gases, but also opens up the opportunity to use important remote sensing and in-situ data information for the inverse modelling approach for regional budgeting. The project also aims at developing new methodologies for greenhouse gas measurements, and promotes technological developments necessary for future Earth-observing satellites.
