Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Raw Curated Payload R01

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Satellite 1 Raw Curated Payload (PREFIRE_SAT1_0-PAYLOAD-TLM) contains the curated raw measurements from one of two PREFIRE Thermal Infrared Spectrometers (TIRS-PREFIRE), which is 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 raw, curated digital number counts for TIRS-PREFIRE aboard PREFIRE Satellite 1 (PREFIRE-SAT1). 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 has a temporal resolution of 0.707 seconds and is available in binary format.

The PREFIRE_SAT2_0-PAYLOAD-TLM collection contains raw, curated digital number counts for the sister instrument aboard PREFIRE-SAT2.

极区辐射能量远红外实验（PREFIRE）卫星1原始精选有效载荷（PREFIRE_SAT1_0-PAYLOAD-TLM）包含了来自两台PREFIRE热红外光谱仪（TIRS-PREFIRE）之一的精选原始测量数据，该光谱仪为推帚式光谱仪，具有63个通道，用于测量约5至53微米的近红外和远红外辐射。大部分极区辐射均位于远红外波段，但尚未进行大规模测量。PREFIRE旨在通过更精确地描述极区辐射来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）上TIRS-PREFIRE的原始精选数字计数。数据检索始于2024年5月，具体日期待定，且仍在进行中。地理覆盖范围全球，数据在极区地区的密度最大。该数据具有0.707秒的时间分辨率，并以二进制格式提供。

PREFIRE_SAT2_0-PAYLOAD-TLM数据集包含PREFIRE-SAT2上姐妹仪器的原始精选数字计数。
