HIRS Level 1C Fundamental Data Record Release 2 - Multimission - Global

This is Release 2 of the Fundamental Data Record (FDR) brightness temperatures from the High Resolution Infrared Radiation Sounder (HIRS) on board NOAA and Metop satellites. The data record covers more than 40 years from 29 October 1978 to 31 December 2022. Release 2 provides recalibrated Level 1c brightness temperatures based on the V4.0 calibration method developed by Cao et al. (2007). This method was implemented into the NWP-SAF software ATOVS and AVHRR processing Package (AAPP). This software was consistently used to recalibrate and reprocess data from all HIRS instruments on board TIROS-N, NOAA-06 to NOAA-19, Metop-A, and Metop-B. Input HIRS data were collected from NOAA/CLASS and ECMWF archives and merged to produce a longer time series of some of the satellites.

本数据集为搭载于美国国家海洋和大气管理局（NOAA）及Metop卫星上的高分辨率红外辐射探测仪（HIRS）所获取的基础数据记录（FDR）亮温数据的第2版发布数据。该数据记录的时间跨度超过40年，涵盖1978年10月29日至2022年12月31日的观测数据。第2版发布数据基于Cao等人（2007年）提出的V4.0定标方法，提供了经过重新定标的Level 1c（1c级）亮温数据。该方法已被集成至数值天气预报卫星应用设施（NWP-SAF）的ATOVS与AVHRR处理套件（AAPP）软件中。该软件被持续用于对所有搭载于TIROS-N、NOAA-06至NOAA-19、Metop-A及Metop-B卫星上的HIRS仪器所获取的数据进行重新定标与再处理。本次输入的HIRS数据采集自NOAA/CLASS及欧洲中期天气预报中心（ECMWF）的档案库，并针对部分卫星开展了数据融合工作，以生成更长时间跨度的时序数据集。
