NASA PREFIRE Project

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Atmospheric Properties from PREFIRE Satellite 1 COG (PREFIRE_SAT1_2B-ATM_COG) is retrieved from data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT1. Dual CubeSats each carry a PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE), a push broom spectrometer with 63 channels measuring mid- and far-infrared (FIR) radiation from approximately 5 to 53 µm. Most polar emissions are in the FIR but have not been measured on a large scale. PREFIRE aims to fill knowledge gaps in the global energy budge...远红外实验极地辐射能（Polar Radiant Energy in the Far InfraRed Experiment，简称PREFIRE）项目的PREFIRE卫星1号COG大气特性数据集（PREFIRE_SAT1_2B-ATM_COG），其数据由搭载于PREFIRE-SAT1的PREFIRE热红外光谱仪（PREFIRE Thermal Infrared Spectrometer，简称TIRS-PREFIRE）采集并反演得到。本次任务采用双立方体卫星（CubeSat）构型，每颗卫星均搭载一台PREFIRE热红外光谱仪（TIRS-PREFIRE），该设备为推扫式光谱仪，配备63个探测通道，可测量约5至53微米波段的中红外与远红外（Far Infrared，简称FIR）辐射。绝大多数极地辐射均处于远红外波段，但目前尚未实现大规模系统性观测。PREFIRE项目旨在填补全球能量收支领域的研究空白……
