Yanovsky, Felix J. (author), Pitertsev, Aleksander A. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)This paper is devoted to discussing peculiarities of W-band cloud radar calibration. After a brief overview of meteorological radar calibration methods for quantitative information retrieval, we focus on problems and their possible solutions with respect to mm-wave radar calibration. The experimental part of the research is based on multi...conference paper 2023

Kiran, Varaha Ravi (author), Ratnam, Madineni Venkat (author), Fujiwara, Masatomo (author), Russchenberg, H.W.J. (author), Wienhold, Frank G. (author), Madhavan, Bomidi Lakshmi (author), Raman, Mekalathur Roja (author), Nandan, Renju (author), Akhil Raj, Sivan Thankamani (author)A better understanding of aerosol–cloud interaction processes is important to quantify the role of clouds and aerosols on the climate system. There have been significant efforts to explain the ways aerosols modulate cloud properties. However, from the observational point of view, it is indeed challenging to observe and/or verify some of these...journal article 2022

Li, B. (author), Basu, S. (author), Watson, S.J. (author), Russchenberg, H.W.J. (author)In the coming decades, the European energy system is expected to become increasingly reliant on non-dispatchable generation such as wind and solar power. Under such a renewable energy scenario, a better characterization of the extreme weather condition ‘Dunkelflaute’, which can lead to a sustained reduction of wind and solar power, is important....journal article 2021

Sarna, K. (author), Donovan, D.P. (author), Russchenberg, H.W.J. (author)Accurate lidar-based measurements of cloud optical extinction, even though perhaps limited to the cloud base region, are useful. Arguably, more advanced lidar techniques (e.g. Raman) should be applied for this purpose. However, simpler polarisation and backscatter lidars offer a number of practical advantages (e.g. better resolution and more...journal article 2021

Yin, Jiapeng (author), Hoogeboom, P. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)Radio frequency interference (RFI) has become a growing concern for weather radar, distorting radar variable estimation. By simultaneously or alternately transmitting the horizontal and vertical polarized waves, polarimetric weather radar can be referred to as SHV radar or AHV radar. The SHV radar can mimic the AHV radar by discarding either...journal article 2021

Li, B. (author), Basu, S. (author), Watson, S.J. (author), Russchenberg, H.W.J. (author)In the near future, wind and solar generation are projected to play an increasingly important role in Europe's energy sector. With such fast-growing renewable energy development, the presence of simultaneous calm wind and overcast conditions could cause significant shortfalls in production with potentially serious consequences for system...journal article 2021

Gatidis, C. (author), Schleiss, M.A. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)The adequacy of the gamma model to describe the variability of raindrop size distributions (DSD) is studied using observations from an optical disdrometer. Model adequacy is checked using a combination of Kolmogorov–Smirnov goodness-of-fit test and Kullback–Leibler divergence and the sensitivity of the results to the sampling resolution is...journal article 2020

Li, B. (author), Basu, S. (author), Watson, S.J. (author), Russchenberg, H.W.J. (author)In the coming decades, both wind and solar power production will be playing increasingly important roles in Europe's energy economy. It is absolutely essential that power grids are resilient against any unusual weather phenomena. One such meteorological phenomenon, "Dunkelflaute", is causing serious concern to the renewable energy industry,...journal article 2020

(author), Oudejans, Erik (author)Weather radar is well recognized as an effective sensor for obtaining the microphysical and dynamical properties of precipitation at high spatial and temporal resolution. Radar calibration is one of the most important prerequisites for achieving accurate observations. In this article, a portable, cost-effective and repeatable radar calibration...journal article 2019

Oude Nijhuis, A.C.P. (author), Unal, C.M.H. (author), Krasnov, O.A. (author), Russchenberg, H.W.J. (author), Yarovoy, Alexander (author)In this article, five velocity-based energy dissipation rate (EDR) retrieval techniques are assessed. The EDR retrieval techniques are applied to Doppler measurements from Transportable Atmospheric Radar (TARA)—a precipitation profiling radar—operating in the vertically fixed-pointing mode. A generalized formula for the Kolmogorov constant is...journal article 2019

Reinoso Rondinel, R. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)In radar polarimetry, the differential phase CDP consists of the propagation differential phase FDP and the backscatter differential phase dhv. While FDP is commonly used for attenuation correction (i.e., estimation of the specific attenuation A and specific differential phase KDP), recent studies have demonstrated that dhv can provide...journal article 2018

(author)The growth of ice crystals in presence of supercooled liquid droplets represents the most important process for precipitation formation in the mid-latitudes. However, such mixed-phase interaction processes remain relatively unknown, as capturing the complexity in cloud dynamics and microphysical variabilities turns to be a real observational...journal article 2018

Rusli, S. (author), Donovan, D.P. (author), Russchenberg, H.W.J. (author)Despite the importance of radar reflectivity (Z) measurements in the retrieval of liquid water cloud properties, it remains nontrivial to interpret Z due to the possible presence of drizzle droplets within the clouds. So far, there has been no published work that utilizes Z to identify the presence of drizzle above the cloud base in an...journal article 2017
