Parameterizing radiative transfer to convert MAX-DOAS dSCDs into near-surface box-averaged mixing ratios [PDF]
Atmospheric Measurement Techniques, 2013 We present a novel parameterization method to convert multi-axis differential optical absorption spectroscopy (MAX-DOAS) differential slant column densities (dSCDs) into near-surface box-averaged volume mixing ratios.

Iodine monoxide in the Antarctic snowpack [PDF]
, 2009 Recent ground-based and space borne observations suggest the presence of significant amounts of iodine monoxide in the boundary layer of Antarctica, which are expected to have an impact on the ozone budget and might contribute to the formation of new ...

Channel Estimation for Ambient Backscatter Communication Systems with Massive-Antenna Reader [PDF]
, 2019 Ambient backscatter, an emerging green communication technology, has aroused great interest from both academia and industry. One open problem for ambient backscatter communication (AmBC) systems is channel estimation for a massive-antenna reader. In this

Linearisation of the effects of spectral shift and stretch in DOAS analysis [PDF]
Atmospheric Measurement Techniques, 2013 Differential Optical Absorption Spectroscopy (DOAS) is a widely used method to quantify atmospheric trace gases from spectroscopic measurements. While DOAS can, in principal, be described by a linear equation system, usually nonlinearities occur, in ...

DoA Estimation via Unlimited Sensing
2020 28th European Signal Processing Conference (EUSIPCO), 2021 Direction-of-arrival (DoA) estimation is a mature topic with decades of history. Despite the progress in the field, very few papers have looked at the problem of DoA estimation with unknown dynamic range. Consider the case of space exploration or near-field and far-field emitters.

Cloud and aerosol classification for 2.5 years of MAX-DOAS observations in Wuxi (China) and comparison to independent data sets [PDF]
Atmospheric Measurement Techniques, 2015 Multi-axis differential optical absorption spectroscopy (MAX-DOAS) observations of trace gases can be strongly influenced by clouds and aerosols. Thus it is important to identify clouds and characterize their properties.

Doa Sebagai Bentuk Pertukaran Ekonomi [PDF]
JSPH (Jurnal Sosiologi Pendidikan Humanis), 2019 This study discusses the practice of social exchange at joint prayer activities at the 'X' Orphanage in Sidoarjo. The joint prayer activities at the 'X' Sidoarjo Orphanage were routinely carried out by two main donors who at the same time became one of the main informants of this study.
