modeling impact of formosat 7 cosmic 2 mission on ionospheric space Weather Monitoring
Journal of Geophysical Research, 2013Co-Authors: I T Lee, Hofang Tsai, Jannyenq Liu, Chaohung Lin, Tomoko Matsuo, Loren C ChangAbstract:[1] For the past decade, the paucity of ionospheric observations has made it almost impossible to reconstruct the three-dimensional structures of global ionospheric electron density. The Formosa Satellite-3/Constellation Observing System for Meteorology, Ionosphere and Climate (FORMOSAT-3/COSMIC, F3/C) constellation has provided ionospheric electron density profiles with high vertical resolution through radio occultation measurements. Slated for deployment starting in 2016, the FORMOSAT-7/COSMIC-2 (F7/C2) constellation will further provide more than 4 times the number of the F3/C occultation soundings. An observing system simulation experiment is conducted to determine the impact of F7/C2 on ionospheric Weather Monitoring. The results first show that the F7/C2 observations can reconstruct 3-D ionospheric structure with a data accumulation period of 1 h, which can advance studies of small spatial/temporal scale variation/signatures in the ionosphere. Comparing to assimilation results of F3/C, the assimilation system significantly reduces the error arising in the models and observations after assimilating synthetic observations of F7/C2. During this observing system simulation experiment period, the averaged root-mean-square error percentage for the results of F7/C2 is about 4.4%, lower than that of F3/C 7.3%. Furthermore, even with an assimilation window of less than 60 min, the F7/C2 RMS errors still yield reliable values compared to the F3/C results. This paper represents a major advance in ionospheric Weather Monitoring for the future mission.

Wireless Portable Microcontroller based Weather Monitoring Station
Measurement: Journal of the International Measurement Confederation, 2015Co-Authors: J.t. Devaraju, K. R. Suhas, H.k. Mohana, Vijaykumar A. PatilAbstract:Weather Monitoring and its forecasting has become vital part of day-to-day life because of its numerous applications in agriculture, farming, fishery, shipping and military operations. Measuring the Weather using conventional or manually operated Weather Monitoring Stations requires skilled labor for operation and demands regular maintenance which invariably increases the life cycle cost of the Weather Monitoring Station. To address these issues, the authors of this paper have attempted to design and implement inexpensive Wireless Portable Weather Monitoring Station using PIC16F887 microcontroller. The implemented Weather Monitoring Station is equipped with sensors to measure Weather variables such as relative humidity, atmospheric pressure, rainfall, solar radiation, wind speed, wind direction, surface and ambient temperature. Besides of these capabilities, the designed Weather Monitoring station also includes some unique features like Modbus communication protocol, which provides seamlessly communication of real time Weather measurements to the base station (PC Laptop) over both wired (RS serial) and wireless (Xbee Pro modules) interfaces. Further, at the base station, the received data is logged and uploaded to an online data server to enable worldwide ubiquitous access to the Weather measurements.
