Abstract The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission carries magnetometers that are dedicated to enhance the satellite’s navigation. After appropriate calibration characterisation of artificial magnetic disturbances, these observations valuable assets characterise natural variability Earth’s field. We describe data pre-processing, calibration, strategy against a hig...

This paper summarizes results obtained for Greenland’s mass balance observed with NASA’s GRACE mission. We estimate a Greenland ice sheet mass loss at -201 ± 19 Gt/year including a discernible acceleration of -8 ± 7 Gt/year between March 2003 and February 2010. The mass loss of glacier systems on the South East of Greenland has slowed down while the mass loss increases toward the North along th...

The timing of grace notes in skilled musical performance at different tempi: a preliminary case study. (2001) The timing of grace notes in skilled musical performance at different tempi: a preliminary case study. Abstract An empirical study is reported which investigates the relationship between musical structure and the timing of 11 grace notes in 45 performances by the same performer of a sho...

one of the important issues in the field of organizational decisions is determine the optimal time of use the equipment. managers should take proper decision to repair, rebuild or replace the equipment, so that the greatest benefit and the least cost to the organization. in the military, moving units, items, equipment and manpower, is the part of the logistics system mission. in this regard, th...

Since March 2002, the GRACE mission provides monthly global maps of geoid time-variations. These new data carry information on the continental water storage, including snow mass variations, with a ground resolution of ~600-700 km. We have computed monthly snow mass solutions from the inversion of the 22 GRACE geoids (04/2002-05/2004). The inverse approach developed here allows to separate the s...

Time series of the Gravity Recovery and Climate Experiment (GRACE) satellite mission have been successfully used to reveal changes in terrestrial water storage (TWS) many parts world. This has hindered interior Tibetan Plateau since derived TWS there are very sensitive selections different available GRACE solutions, filters remove north-south-oriented (N-S) stripe features observations. resulte...

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is dedicated to the fine spectroscopy (∆E: 2 keV FWHM @ 1.3 MeV) and fine imaging (angular resolution: 12 FWHM) of celestial gamma-ray sources in the energy range 15 keV to 10 MeV with concurrent source monitoring in the X-ray (3 35 keV) and optical (V, 550 nm) range. The mission is conceived as an observatory led by ESA with contri...
