User manual VAISALA LIGHTNING NETWORK PERFORMANCE EVALUATION PROGRAM DATASHEET

[. . . ] [. . . ] A scientific lightning expert will conduct a detailed analysis to determine areas for network improvement, which include: · Verificationofthereliabilityof the output data · Confirmationthatthenetwork environment has not changed · Makingcertainthatthesystemis properly configured · Ensuringthatneworupgraded sensors are configured and contributing to the network in the most effective way Why and When An NPEP should be performed upon network installation for optimal performance and then again under the following circumstances: · Eighteenmonthshavepassedsince the last NPEP · Thesitehasundergoneaphysical change (buildings have been erected, trees planted, etc. ) · Asensorhasbeenrotated or moved · Thenumberofsensorsinthe network has changed · Highsensorqaerrorsinlogfiles are being generated by the central processor Network detection efficiency as determined from observable parameters, in order to verify performance Network corrections that can be entered directly into the central processor database Comparison of location accuracy before and after the new site error corrections are applied to the central processor Required changes in the patented location algorithm configuration file Lightning Network Performance Evaluation Program (NPEP) Below is an example of network performance before and after a Vaisala NPEP Vaisala NPEP Service Levels LS7001 (LF network) Service Quick Check What We Provide Before a Vaisala NPEP Complete NPEP Graphing of problem areas from sensorqa log files Summary and recommendations Quote for additional work Graphing of problem areas from sensorqa log files Site error corrections Random error of angle, time, and signal amplitude Graphing of problem areas from sensorqa log files Site error corrections Random error of angle, time, and signal amplitude Gain corrections (for LPATS sensors) Tuning located . cfg file Analysis of CHI-square distribution Cloud to Ground relative Detection Efficiency (DE) map Updated Location Accuracy (LA) map Add or Move Sensor Complete NPEP LS8000 (LF + VHF Network) Service Quick Check What We Provide Includes above LF network analysis plus the below VHF analysis Graphing of RDAM using B$ data Includes above LF network analysis plus the below VHF analysis Graphing of RDAM using B$ data Antenna rotation correction Raw sensor data analysis of antenna diagrams, time series plots, outage times, directional noise sources Modulus (sin2 + cos2) Includes above LF network analysis plus the below VHF analysis Graphing of RDAM using B$ data Antenna rotation correction Raw sensor data analysis of antenna diagrams, time series plots, outage times, directional noise surfaces Modulus (sin2 + cos2) Analysis and fixing of sdd. cfg file After a Vaisala NPEP · Higherdetectionefficiency · Betterclusteringoflightningeventsorlightning locationaccuracy Add or Move Sensor For more information or to order a Vaisala NPEP report, please contact your Vaisala sales representative or email our Thunderstorm Support desk at thunderstorm. support@vaisala. com For more information, visit www. vaisala. com or contact us at sales@vaisala. com Ref.
