bl_type: An algorithm to objectively diagnose boundary-layer using Doppler lidar and sonic anemometer data

Doppler lidar is a powerful tool for the remote sensing of the boundary layer. bl_type is a package that can diagnose boundary-layer type from Doppler lidar and sonic anemometer data. There are 9 types, based on the types used in the UK Met Office boundary-layer scheme (Lock et al., 2000), that can be diagnosed (see below) and for each time a probability of each type is calculated. Full details of the algorithm can be found in Harvey et al. (2013).
