Radar dataset for 'Two layers of melting ice particles within a single radar bright band' study

<p>Radar dataset for &#39;Two layers of melting ice particles within a single radar bright band&#39; study.</p> <p>Site:&nbsp;The University of Helsinki Station for Measuring Ecosystem-Atmosphere Relation II (SMEAR II),&nbsp;Hyyti&auml;l&auml;, Southern Finland (61.845N, 24.287E).</p> <p>Time: April 18th - 19th, 2018&nbsp;UTC.</p> <p>Instruments: Vertically pointing W- and C- band radars (HYDRA-W and -C).&nbsp;In addition to reflectivity, LDR, Doppler velocity and spectrum width that are observed by both radars, HYDRA-W records Doppler spectra. HYDRA-C operates with the maximum unambiguous Doppler velocity of 4.98 m/s. The settings of the HYDRA-W observations depend on the range. Below 996 m, the range resolution is 25.5 m and Doppler spectra are computed by using a 1024-point FFT with the Nyquist velocity of 10.24 m/s. For the heights between 996 m and 3577 m, the range resolution is kept the same, while the Doppler spectrum is computed using 512-point FFT with the Nyquist velocity of 5.12 m/s. For the heights above 3577 m, the range resolution is decreased to 34 m, while the Doppler measurements are done using the same settings. The temporal resolution of HYDRA-C and HYDRA-W measurements are 1.37 and 3.35 s, respectively.&nbsp;</p>
