Analysis of cloud-to-ground lightning density in Brazil

The importance of information on cloud-to-ground lightning density to the Brazilian society has been increasing in importance due to their use in many different applications, in particular for the Brazilian Electric Sector. However, the information needs to be precise otherwise their use in engineering application does not provide large benefits. This article describes the present knowledge about cloud-to-ground lightning density data in Brazil and the possibilities to improve this information using new different sources of lightning data. Since all sources of information have intrinsic limitations, the use of them together may be the best way to get more precise information to meet the present needs. To do that, however, it is required to know in details the limitations involved in each source of data.
