[1] Clear sky downwelling longwave radiation (Rldc) and cloudy sky downwelling longwave radiation (Rld) formulas were tested across eleven sites in Florida. The Brunt equation, using air vapor pressure and temperature measurements, provides the best Rldc estimates with a root mean square error of less than around 12 Wm 2 across all sites. The Crawford and Duchon’s cloudiness factor with Brunt e...
The DENIS and 2MASS near infrared surveys are presented. Their applications in extragalactic astronomy and cosmology are listed. The prospects for a rapid spectroscopic followup survey of a near infrared selected sample of nearly 10 galaxies are illustrated with MonteCarlo simulations.
A significant source of uncertainty in the prediction of the apparent optical properties of the ocean is the geometrical distribution of the radiance field and its variation with respect to time and space; this uncertainty directly affects attempts to use measurements of reflectance and attenuation for the diagnosis of ocean constituents. Uncertainties in the time and depth dependent variations...
We present a project to map the artificial sky brightness in Europe in the main astronomical photometrical bands with a resolution better than 3 km. The aim is to understand the state of night sky pollution in Europe, to quantify the present situation and to allow future monitoring of trends. The artificial sky brightness in each site at a given position on the sky is obtained by the integratio...
We present a method to map the artificial sky brightness across large territories in astronomical photometric bands with a resolution of approximately 1 km. This is useful to quantify the situation of night sky pollution, to recognize potential astronomical sites and to allow future monitoring of trends. The artificial sky brightness present in the chosen direction at a given position on the Ea...
* Big Sky Institute, 106 AJM Johnson Hall, Montana State University, Bozeman, MT 59717-3490 USA. [email protected] Department of Land Resources and Environmental Sciences, Montana State University, Bozeman, MT, USA. Abstract Postindustrial rises in CO2 have the potential to confound the interpretation of climatically sensitive tree-ring chronologies. Increased growth rates observed during the 2...
In all our experiments, at training time we pick top 2000 RPN generated 3D proposals using NMS (non-maximum suppression). At test time we select top 1000 3D proposals. However, a lower number of proposals, e.g. top 300 proposals does not effect the detection performance, and increase the test time detection speed significantly. In Section 3.2, we show that extracting less number of 3D proposals...
The Australian SKA Pathfinder (ASKAP) is a new radio-telescope being built in Western Australia. One of the key surveys for which it is being built is EMU (Evolutionary Map of the Universe), which will make a deep (∼10 μJy/bm rms) radio continuum survey covering the entire sky as far North as +30◦. EMU may be compared to the NRAO VLA Sky Survey (NVSS), except that it will have about 45 times th...
