Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 telemetry R01

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Telemetry (PREFIRE_SAT1_0-BUS-TLM) contains positioning and pointing information for one of two PREFIRE polar orbiting CubeSats. Both CubeSats 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 budget by more accurately characterizing polar emissions. This information will then be assimilated into global circulation and other climate models to predict future climates more accurately.

This collection contains the time, beta angle, orbit position and velocity, and quaternion of PREFIRE Satellite 1 (PREFIRE-SAT1). Combined with a Digital Elevation Map, these telemeters are used to geolocate PREFIRE data on the Earth’s surface.

Data retrieval started in May TBD, 2024, and is ongoing. Geographic coverage is global, with the greatest concentration of data in the polar regions. This data is retrieved at a frequency of 1Hz and is available in CSV format.

Positioning and pointing information for the sister satellite, PREFIRE-SAT2, can be found in the PREFIRE_SAT2_0-BUS-TLM collection.

极地辐射能远红外实验（PREFIRE）卫星1遥测数据（PREFIRE_SAT1_0-BUS-TLM）包含了两颗PREFIRE极地轨道立方卫星之一的位置和指向信息。这两颗立方卫星均搭载了PREFIRE热红外光谱仪（TIRS-PREFIRE），该光谱仪为推帚式光谱仪，具有63个通道，测量约5至53微米的中远红外（FIR）辐射。极地辐射大多位于FIR波段，但尚未进行大规模测量。PREFIRE项目旨在通过更精确地描述极地辐射，填补全球能量预算的知识空白。这些信息随后将被纳入全球环流模型和其他气候模型中，以更准确地预测未来气候。

本数据集包含PREFIRE卫星1（PREFIRE-SAT1）的时间、β角、轨道位置和速度以及四元数。结合数字高程图，这些遥测数据被用于在地球表面进行PREFIRE数据的地理定位。

数据检索始于2024年5月待定日期，并持续进行。地理覆盖范围全球，数据在极地地区的密集度最高。数据以1Hz的频率进行检索，并以CSV格式提供。

PREFIRE卫星2（PREFIRE-SAT2）的位置和指向信息可在PREFIRE_SAT2_0-BUS-TLM数据集中找到。
