Abstract
The first weather radar campaign over Lima, the capital of Peru, a desertic area on the western side of the Peruvian Andes, was carried out to study the occurrence of rain events in summer 2018. The weather radar was installed strategically and was able to overlook three river basins: Rimac, Chillón, and Lurin. An X-band radar (PX-1000) was used, which operates at 9.55 GHz. PX-1000 was built by the Advanced Radar Research Center (ARRC) at the University of Oklahoma (U.S.A.). The radar operated from January 26th to April 1st, 2018, at Cerro Suche located 2910 m ASL and 55 km from the city of Lima. The PX-1000 performed plan-position-indicators (PPI) for elevations starting at 0° up to 20°. The data presented here were obtained using a three-dimensional constant-altitude plan-position-indicator (3D CAPPI), which was generated by high resolution (250 m) nearest point algorithm.

Present dataset comes from the project “Hydrogeodynamic modeling (rainfall, mudslides and landslides) in Chosica, Lima, Peru” funded by FONDES. Special thanks to Advanced Radar Research Center (ARRC) of the University of Oklahoma for providing the PX-1000 weather radar. The Jicamarca Radio Observatory is a facility of the Instituto Geofísico del Perú operated with the support from the NSF AGS-1433968 through Cornell University. Thanks to the Peruvian PPR068 programme “Reducción de vulnerabilidad y atención de emergencias por desastres” for financial support of our work. This work was done using the computational resources, HPC-Linux Cluster, from the Laboratorio de Dinámica de Fluidos Geofísicos Computacionales at Instituto Geofísico del Perú (grants 101-2014-FONDECYT, SPIRALES2012 IRD-IGP, Manglares IGP-IDRC, PP068 program).
