operational atmospheric specifications are enabling increasingly accurate models of regional range (15–250 km) and remote (> 250 km) infrasound propagation through atmospheric waveguides particularly in the troposphere, stratosphere, and thermosphere (e.g., Drob2019; Waxler and Assink2019; Schwaiger ...
After receiving the data sent by the satellite, the GPS terminal can determine the current position through solution, and output the data in NMEA0183 grid and WGS-84 coordinate system. Some readers may ask, what if the satellite breaks down, isn't GPS going to be inaccurate? In fact, this...
Allowing some historical perspective shows that the IPCC is wrong to label the recent temperature changes ‘unprecedented’. They are not unusual in magnitude, direction or rate of change, which should diminish fears that recent climate change is somehow catastrophic. To understand how climate has va...
we should be able to obtain a value for λ. The N terms are likely to contaminate the result for short datasets,but provided the N terms are uncorrelated to T, the regression should give the correct value for λ, if the dataset is long enough...
