Anthropogenic radio frequency interference (RFI) is an increasing problem in microwave remote sensing radiometry. Therefore, there is growing interest in RFI counteraction methods, including detection and blanking. In this study, the performance of p

Many halo arcs are caused by pyramidal crystals that have {1 0 -1 1} crystal faces. We treat halo arcs arising from pyramidal crystals that fall in the air with their c axes vertically oriented. To our knowledge only 6 of the 12 possible halo phenome

A marginally known pyramidal halo that can be e.g. referred as “23° parroid” is unexpectedly emerging at least as one of the three most frequent rare halos. It appears that during this century hundreds of high solar elevation 23° parroids have
