Satellite television as a mass medium - Satellite Communications Pocket Book - 13ELSEVIERSatellite Communications Pocket Book
The speed of orbiting satellite is the result of the balance between the tangential velocity of the satellite and the centripetal force acting towards the center of the Earth. The orbital velocity in terms of mathematical expression is a function of the mass of ...
Traditional Earth orbiting satellites used for scientific studies and weather monitoring tend to be large and expensive, with a mass of hundreds to thousands of kg and a cost of hundreds of millions of USD. Recent examples include the NOAA Joint Polar Satellite System’s JPSS-1 (2200 kg and...
3a) are estimated with a Monte Carlo simulation, where we apply the aqueous methane concentrations to a corresponding discharge rate. The discharge rate across the freezing season is calculated from the icing area at each sampled site (measured with satellite imagery), the average icing depth (...
3a), while the model mean bias with respect to the AERONET observations changes from −0.084 in the [CONTROL] simulation to +0.039 in the [MET + VEG] simulation (Fig. 3b). Overall, with respect to satellite-retrieved and ground-based measurements of AOD, the default model shows ...
The O/OREOS 3U satellite (\(3~\mbox{dm}^{3}\) volume total) consists of a control bus and two high-capability science payloads, each contained in 1U cubesat module (Fig. 12). Fig. 12 NASA Ames’s O/OREOS triple-cubesat (with the de-orbit mechanism deployed) achieved full mission...
Overall, the modeled distribution of atomic sodium in WACCM agrees well with both ground-based and satellite observations. Given the strong sensitivity of the sodium layer to dynamical motions, reproducing its variability provides a stringent test of global models and should help to constrain key ...
The themes of traditional fables often deal with simple truths about everyday life. However, Cason’s theme is a more weighty69(warn) about environmental destruction. Carson proves that a simple lyric form that has been passed down through the ages...
a Zonal- and time-mean precipitation and b 99.9th percentile of 3-hourly precipitation, for the high-resolution simulation (hi-res; blue), and the coarse resolution simulation with the random forest (RF) parameterization (x8-RF; orange dashed–dotted) and without the RF parameterization (x8; ...
More recent syntheses suggest that glacier mass loss has been the overall trend since the 1950s with the greatest rate of glacier area loss since ~200013. For the south side of Mt. Everest, combined photogrammetric and satellite imagery reveals thinning greater than 100 m up to 5700 m ...
