We conduct the first 4D-Var inversion of NH3 accounting for NH3 bi-directional flux, using CrIS satellite NH3 observations over Europe in 2016. We find posterior NH3 emissions peak more in springtime than prior emissions at continental to national sc

A study on harmonizing total ozone assimilation with multiple sensors

Autor: Y. J. Rochon, Michael Sitwell, Young-Min Cho

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 9431-9451 (2019)

The impact of assimilating total column ozone datasets from single and multiple satellite data sources with and without bias correction has been examined with a version of the Environment and Climate Change Canada variational assimilation and forecas

Coaxing cosmic 21 cm fluctuations from the polarized sky usingm-mode analysis

Autor: J. Richard Shaw, Michael Sitwell, Albert Stebbins, Ue-Li Pen, Kris Sigurdson

Publikováno v: Physical Review D. 91

In this paper we continue to develop the m-mode formalism, a technique for efficient and optimal analysis of wide-field transit radio telescopes, targeted at 21 cm cosmology. We extend this formalism to give an accurate treatment of the polarised sky
