GOME data analysis and ground-based observations in the Mediterranean area during Etna volcano activity
The ozone decline at mid-latitude could be explained by three different and concomitant mechanisms: O3 loss inside the arctic vortex and subsequent transport of low-level ozone air masses to mid latitudes, local process, chlorine activation due to extra-vortices heterogeneous reactions. A collaborative study is started with the aim to address the first two questions by means of analysis of sate...
متن کاملPrecision simulation of ground-based lensing data using observations from space
Current and upcoming wide-field, ground-based, broad-band imaging surveys promise to address a wide range of outstanding problems in galaxy formation and cosmology. Several such uses of ground-based data, especially weak gravitational lensing, require highly precise measurements of galaxy image statistics with careful correction for the effects of the point spread function (PSF). In this paper,...
متن کاملCloud Phase Determination Using Ground-Based AERI Observations at SHEBA
A new technique for ascertaining the thermodynamic cloud phase from high-spectral-resolution ground-based infrared measurements made by the Atmospheric Emitted Radiance Interferometer (AERI) is presented. This technique takes advantage of the differences in the index of refraction of ice and water between 11 and 19 mm. The differences in the refractive indices translate into differences in clou...
متن کاملFrom joint analysis of Hipparcos and ground-based observations
Two methods are considered for the improvement of the ephemerides of the asteroids observed by the Hipparcos satellite. They utilize different combinations of ground-based and space-based data. In particular, we develop a method based on an analysis of the variance matrix in the least-squares solution of Hipparcos observations taken alone. Application and comparison of the results for (2) Palla...
متن کاملMillimetric ground-based observations of Cosmic Microwave Background Anisotropy
First results of a Cosmic Microwave Background (CMB) anisotropy experiment conducted at the Observatorio del Teide (Tenerife, Spain) are presented. The instrument is a four channel (3.1, 2.1, 1.3 and 1.1 mm) He bolometer system coupled to a 45 cm diameter telescope. The resultant configuration is sensitive to structures on angular scales ∼ 1◦ − 2◦. We use the channels at the two highest frequen...
