GPS radio occultations
The occurrence of sporadic E (Es) layers has been a hot scientific topic for a long time. The GNSS (global navigation satellite system)-based radio occultation (RO) has proven to be a powerful technique for detecting the global Es layers. In this paper, we focus on some cases of complex Es layers based on the RO data from multiple missions processed in UCAR/CDAAC (University Corporation for Atm...

متن کاملAdapting images to observers
Adaptation exerts a continuous influence on visual coding, altering both sensitivity and appearance whenever there is a change in the patterns of stimulation the observer is exposed to. These adaptive changes are thought to improve visual performance by optimizing both discrimination and recognition, but may take substantial time to fully adjust the observer to a new stimulus context. Here we e...
متن کاملLunar Occultations of Stars with Exoplanet Candidates
We investigate the potential of lunar occultations for the detection of very faint companions, and in particular for the possibility of detecting extrasolar planets. We review the basic concepts of the method, and discuss the quantities which are relevant for this particular application. The near-infrared range, and in particular the K and L bands (2.2 and 3.6m), ooer the best dynamic range. We...
متن کاملThe Orbit and Occultations of Kh 15d
The unusual flux variations of the pre–main-sequence binary star KH 15D have been attributed to occultations by a circumbinary disk. We test whether or not this theory is compatible with newly available data, including recent radial velocity measurements, CCD photometry over the past decade, and photographic photometry over the past 50 years. We find the model to be successful, after two refine...
