Evaluation of BrasilDAT relative detection efficiency based on LIS observations and a numeric model

The BrasilDAT total lightning detection network provides the capability of detecting total lightning on a continental scale. An understanding of the detection efficiency of BrasilDAT is necessary for use of total lightning data in applications such as severe weather detection and derivation of rainfall rates. BrasilDAT relative detection efficiency is studied by comparing lightning flashes seen by the network and by the Lightning Imaging Sensor (LIS) on board of the low earth orbit satellite TRMM. Also projections of BrasilDAT relative detection efficiencies will be computed based on calculations of ELAT's 4th generation relative detection efficiency model.
