This product displays the Cloud Optical Thickness (COT) around the globe. Clouds play a crucial role in the Earth's climate system and have significant effects on trace gas retrievals. The cloud optical thickness is retrieved from the O2-A band using the ROCINN algorithm. 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).

Ausgehend von den ueberdimensionierten Landnutzungsstrukturen auf dem Gebiet der ehemaligen DDR sollen Konzepte fuer eine oekologisch und oekonomisch sinnvolle neue Landnutzungsstruktur unter den besonderen Bedingungen in den neuen Bundeslaendern entwickelt werden. Hierzu werden zur Zeit anhand von Fallbeispielen ausgewaehlter LPG'en die variierenden Standortfaktoren (Mittelgebirgslagen, Sandboeden, Loessboeden) untersucht, um darauf aufbauend zweckmaessige Landnutzungsstrukturen zu entwickeln. Erfasst und dargestellt wird die rezente Flaechennutzung unter besonderer Beruecksichtigung schutzwuerdiger Natur- und Landschaftsbestandteile sowie die natuerlichen Standorteigenschaften im Hinblick auf Klima, Boden, Geologie, Wasserhaushalt etc. anhand von Gelaendeaufnahmen, Karten, Luftbildaufnahmen und Literaturauswertungen. Weitere Daten zur Agrarstruktur und der amtlichen Statistik fliessen in die Untersuchung ein. Im Anschluss an die Datenerhebung und Darstellung schliesst sich eine Bewertung der untersuchten Gebiete fuer verschiedene Nutzungsansprueche im Sinne einer Mehrfachnutzung an. Ausgehend von den Bewertungen sollen alternative, standortspezifische Flaechennutzungskonzeptionen entwickelt werden. Aus EDV-technischer Sicht wird zu diesem Projekt ein begleitendes DV-Instrumentarium und die entsprechende Analysemethodik fuer raumbezogene Daten auf der Basis geographischer Informationssysteme entwickelt. Hierzu zaehlt sowohl die digitale als auch die datenbankgestuetze Erfassung der vielfaeltigen Flaechen- und Rauminformationen. Zu diesem Zweck wird ein PC- gestuetztes Geographisches Informationssystem eingesetzt. Methoden der Datenanalyse und Datentransformationen sollen in einem weiteren Projektabschnitt zeigen, ob und inwieweit bestehende GIS in der Lage sind, den vielfaeltigen Auswertungs- und Abfragewuenschen gerecht zu werden. Hierzu zaehlt beispielsweise die quantitative Bestimmung von Konfliktpotentialen verschiedener Nutzungsansprueche, die Simulation alternativer Planungsvarianten oder die Optimierung der Flaechennutzung an ausgewaehlten Standorten (Freizeit, Erholung, Hecken, Feldgehoelze).
