A torrential flood event occurred over the complex terrain in Zhejiang on 23 June 2015 is investigated utilizing the first routinely operational C-band polarimetric radar in China. The polarimetric radar quantitative precipitation estimation (QPE) performance is verified using a local rain gauge network, and the microphysical characteristics of the rainstorm are revealed based on polarimetric radar variables. The results show that (i) radar QPE estimator based on KDP performs the best among all estimators; (ii) the rainstorm upon the rainfall center area was dominated by small-moderate sized raindrops with mean volume diameter less than 2 mm, but high raindrop concentration with log10(Nw) exceeding 5 mm-1m-3, resulting in rather high liquid water content; (iii) small hailstones were falling and melting upon the intense rainfall area between gauge stations, which compounded the complex precipitation structure and enhanced raindrop concentration.

UNLABELLED: As a common post-translational modification, protein glycosylation plays an important role in many biological processes, and it is known to be associated with human diseases. Mass spectrometry (MS)-based glycomic profiling techniques have been developed to measure the abundances of glycans in complex biological samples and applied to the discovery of putative glycan biomarkers. To automate the annotation of glycomic profiles in the liquid chromatography-MS (LC-MS) data, we present here a user-friendly software tool, MultiGlycan, implemented in C# on Windows systems. We tested MultiGlycan by using several glycomic profiling datasets acquired using LC-MS under different preparations and show that MultiGlycan executes fast and generates robust and reliable results.
