1 | Chapman, David S. | Global warming - just hot air? | We know from weather station records that Earth's surface temperature has increased on average by 0.6 degrees C in the last 100 years. The 1990s have been the warmest decade on record. Over the same period, global sea level has increased by 10-20 cm. We know also that planet Earth has an atmosphere ... | Greenhouse Effect; Climate change | 1998 | |
2 | Chapman, David S. | Techniques, analysis, and noise in a Salt Lake Valley 4D gravity experiment | Repeated high-precision gravity measurements using an automated gravimeter and analysis of time series of 1-Hz samples allowed gravity measurements to be made with an accuracy of 5 μGal or better. Nonlinear instrument drift was removed using a new empirical staircase function built from multiple ... | Gravity measurements | 2008 |
