Multiple-regression analyses have been performed on 32 years of total ozone column data that was spatially gridded with a 1× 1.5 resolution. The total ozone data consist of the MSR (Multi Sensor Reanalysis; 1979–2008) and 2 years of assimilated SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) ozone data (2009–2010). The two-dimensionality in this data set allows...

We investigate how the Madden-Julian Oscillation (MJO), dominant mode of tropical subseasonal variability, modulates lifecycle cool-season North Pacific atmospheric rivers (ARs). When enhanced (suppressed) convection center is located over Indian Ocean (western Pacific), more AR events originate eastern Asia and with fewer subtropical northern Pacific. western (Indian Ocean), opposite changes o...

Abstract. Atmospheric blocking is a circulation pattern that describes the presence of large-scale, persistent anticyclones, which have potential to bring severe impacts at surface. However, dynamical behaviour blocks still not fully understood. For example, factors determine persistence events are clear. In this study, relationship between and smaller-scale transient anticyclonic eddies examin...

The GRACE and GRACE-FO missions have provided an unprecedented quantification of large-scale changes in the water cycle. However, it is still open problem how these missions' data sets can be referenced to a ground truth. Meanwhile, stationary optical clocks show fractional instabilities below $10^{-18}$ when averaged over hour, continue improved terms precision accuracy, uptime, transportabili...

The accurate estimation of the zero-height geopotential level in a local vertical datum (LVD) is critical for linking traditional height reference systems to global system. In this paper, we investigate theoretical and practical challenges involved determining offset between North American (NAVD) (GVD). Drawing on classical theory system physical geodesy, define derive rigorous formulas its cal...

The International Association of Geodesy (IAG) aims to establish the Height Reference System (IHRS) as one its primary scientific objectives. Central realization IHRS is global vertical datum unification, which requires connection existing local height reference systems (VHS) robustly and consistently. However, conventional methods are not suitable for estimating offsets between two distant sys...

We present and characterize the performance of a new remote sensing concept extrapolated from the GPS occultation concept in which we choose the signal frequencies to determine profiles of atmospheric water, ozone, temperature, geopotential of atmospheric pressure surfaces and clouds.
