NCAR/EOL ISFS Disdrometer histograms


Particle size and fall speed histograms measured by the OTT optical disdrometers collected by the NCAR/EOL Integrated Surface Flux System (ISFS) during the RELAMPAGO field campaign. The distrometers were deployed at 10 sites.  Size distribution data (available every minute) are not part of standard ISFS data processing, but have been created as separate data files and will be available as a companion dataset. Data are made available as monthly ASCII files. Refer to ISFS operations during Relampago documentation for a readme information.
