We use 2005–2009 satellite observations of formaldehyde (HCHO) columns from the OMI instrument to infer biogenic isoprene emissions at monthly 1 × 1 • resolution over the African continent. Our work includes new approaches to remove biomass burning influences using OMI absorbing aerosol optical depth data (to account for transport of fire plumes) and(More)
This paper reports on the development of Neural Network algorithms for ozone concentration profiles retrieval from ESA-Envisat SCIAMACHY measurements. We present and discuss some preliminary results obtained by training our Nets with WOUDC/SHADOZ ozonesondes data; dataset preparation and matching of SCIAMACHY level 1b data with ozonesonde measurements is(More)
In this paper, we propose a system for monitoring abnormal NO 2 emissions in troposphere by using remote-sensing sensors. In particular, the system aims at estimating the amount of NO 2 resulting from biomass burning by exploiting the synergies between the GOME and the ATSR-2 sensors mounted on board of the ERS-2 satellite. Two different approaches to the(More)
[1] Traditionally the Earth's reflectance has been assumed to be roughly constant, but large decadal variability, not reproduced by current climate models, has been reported lately from a variety of sources. We compare here the available data sets related to Earth's reflectance, in order to assess the observational constraints on the models. We find a(More)
A simple technique for the fast retrieval of the total ozone column amount from GOME (Global Ozone Monitoring Experiment) uncalibrated spectra is described in detail. The TIDAS (Temperature Independent Differential Absorption Spectroscopy) technique uses GOME's capability of measuring atmospheric spectra over a broad wavelength range with high spectral(More)
The monitoring of water vapor from space is a difficult task due to its strong spatial variability and its complex spectroscopic structure. Until about the turn of the century only a very limited number of instruments such as SSMI or TOVS were able to provide total column water vapor measurements on a global scale and for sufficiently long time series.
