In 1980's Russian scientist Gorny found some short lived thermal anomalies from satellite image before earthquake in central Asia [1], Since then many scientists began to study this thermal anomaly with satellite data in China, Japan, India, Iran and Algerian earthquakes [2][3][4][5]. Ouzounov [6] used outgoing long wave earth radiation (OLR) data and studied the OLR anomalous variations prior ...

The ionosphere plays an important role in satellite navigation, radio communication, and space weather prediction. However, it is still a challenging mission to develop model with high predictability that captures the horizontal-vertical features of ionospheric electrodynamics. In this study, multiple observations during 2005–2019 from space-borne global navigation system (GNSS) occultation (RO...

[1] We conduct experiments with an ice-ocean model to answer the question whether and to what degree unusually clear skies during the summer of 2007 contributed to the record sea ice extent minimum in the Arctic Ocean during September of 2007. Anomalously high pressure over the Beaufort Sea during summer 2007 appears associated with a strong negative cloud anomaly. This anomaly is two standard ...

The use of state-of-the-art hyperspectral sensors--such as the Atmospheric InfraRed Sounder (AIRS) on NASA’s polar-orbiting Aqua satellite--to retrieve high vertical resolution thermodynamic profiles and their subsequent assimilation into forecast models holds promise in improving weather predictions. This improved vertical resolution over previous capabilities results from the use of thousands...

The Madden–Julian oscillation (MJO) is known as the dominant mode of tropical intraseasonal variability and has an important role in the coupled-atmosphere system. This study uses numerical model experiments to investigate the influence of the MJO activity on weather predictability in the midlatitudes of the Northern Hemisphere. The National Aeronautics and Space Administration (NASA) Goddard L...

As one significant component of space environmental weather, the ionosphere has to be monitored using Global Positioning System (GPS) receivers for the Ground-Based Augmentation System (GBAS). This is because an ionospheric anomaly can pose a potential threat for GBAS to support safety-critical services. The traditional code-carrier divergence (CCD) methods, which have been widely used to detec...

Abstract Plasma variations in the geospace environment driven by solar wind–magnetosphere interactions are one of major causes satellite anomaly. To mitigate effect anomaly, risk space weather disturbances predicted forecasting needs to be known advance. However, anomaly owing is not same for all satellites, because depends only on itself but also design and materials individual satellites. Fro...
