ICECAPS-ACE: present weather taken at Summit Station Greenland
Abstract
This dataset contains horizontal optical range and present weather codes at Summit Station, Greenland. Measurements were made using Biral SWS-100 visibility and present weather sensor.
These data were collected as part of the joint Natural Environmental Research Council (NERC) and US National Science Foundation (NSF) -funded Integrated Characterisation of Energy, Clouds, Atmospheric state, and Precipitation at Summit - Aerosol Cloud Experiment (ICECAPS-ACE) project.
These data were continued through the 3 year extension to the ICECAPS-ACE project called ICECAPS-MELT.
For these observations hood and window heaters were on continuously and the sensor receiver head was oriented due North.
