  "account": "The CERES Radiation Validation Experiment (CRAVE) utilizes various radiometric and meteorological instruments at Granite Island, Michigan and NASA LaRC to support its validation efforts. At the Granite Island, MI (GIM) station, the experiment employs a pyrheliometer (Kipp & Zonen, CH1 or CHP1), a pyranometer (Kipp & Zonen, CM21 or CM22), a pyrgeometer (Kipp & Zonen, CGR4 or CG4), and temperature/relative humidity sensors (Vaisala, HMP60) to measure direct, diffuse, and global shortwave irradiance, as well as diffuse and global longwave irradiance. Meteorological data at the GIM station includes barometric pressure (Vaisala, PTB110), ambient temperature, and ambient relative humidity. Additionally, the experiment features a Li-Cor, LI-190R for Photosynthetic Active Radiation (PAR) measurements and a Middleton, SP02 sunphotometer for aerosol optical depth analysis. At NASA LaRC (LRC), CRAVE instruments include a pyrheliometer (Kipp & Zonen, CH1 or CHP1), a pyranometer (Kipp & Zonen, CM22), a pyrgeometer (Kipp & Zonen, CM22), and temperature/relative humidity sensors (Vaisala, HMP60).",
