A Comparison of Processing Methods for the Oklahoma Lightning Mapping Array
نویسندگان
چکیده
The Oklahoma Lightning Mapping Array (OKLMA) has consisted of 17 Very High Frequency (VHF) sensors in two separate clusters separated by roughly 150 km since 2012. This large footprint is expected to benefit the spatial coverage, sensitivity and accuracy network (e.g., Chmielewski & Bruning, 2016, https://doi.org/10.1002/2016jd025159; Koshak et al., 2018, https://doi.org/10.1175/jtech-d-17-0041.1). unique configuration facilitates evaluation treating as a single, unified network. Network operators may wish do this when processing networks close proximity or for temporary extensions during field projects. 0000–0600 UTC period on 16 June 2019 included millions VHF sources thousands flashes from isolated storms mesoscale convective system. 0300–0700 12 contained single storm interest proceeding scattered activity. solutions their grouped OKLMA are compared those generated combination each operating separate, independent networks. not only required substantially longer time, but also resulted lower more noise, suggesting that theoretical model high with LMA apply configuration. Additionally, relatively few (<10%) observed cluster matched source opposite cluster, mapped were most often unique.

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
