The cold atomic gravimeter (CAG) has the advantage of high measurement accuracy and does not need to be calibrated on a regular basis. To achieve atom interference, it is first necessary cool trap atoms by magneto-optical (MOT). However, there are many types MOTs, their trapping cooling results directly affect thus, CAG. MOTs should designed or selected correctly for different application needs...

The recently upgraded barotropic tidal model TiME is employed to study the influence of fundamental processes, chosen resolution, and bathymetric map on achievable accuracy, exemplary for M2 tide. Additionally, newly introduced pole-rotation scheme allows estimate model’s inherent precision (open ocean rms: 0.90 cm) enables studies Arctic domain without numerical deviations originating from pol...

In this work, we study the kinetics of thermal decomposition MgCO3 in form particles known size. experiments, material is heated to a temperature vacuum oven, and it characterized, both before after heating, by infrared spectroscopy gravimetry. The agreement between results two techniques excellent. These are rationalized means model based on Languir’s law, comparison with experiments allows us...
