IMERG-Final 버전 '06'은 2021년 9월에 생산이 중단되었습니다.
버전 '07'은 2022년 9월에 출시될 예정입니다.
Global Precipitation Measurement (GPM)는 3시간마다 전 세계의 비와 눈에 관한 차세대 관측 데이터를 제공하는 국제 위성 미션입니다. GPM용 통합 다중 위성 검색 (IMERG)은 GPM 컨스텔레이션의 모든 수동 마이크로파 기기의 데이터를 결합하여 강우량 추정치를 제공하는 통합 알고리즘입니다.
이 알고리즘은 전 세계 TRMM 및 GPM 시대에 대해 미세한 시간 및 공간 규모로 모든 위성 마이크로파 강수량 추정치와 마이크로파 보정 적외선 (IR) 위성 추정치, 강수량 게이지 분석, 잠재적으로 기타 강수량 추정치를 교정하고 병합하고 보간합니다.
이 시스템은 각 관측 시간에 대해 여러 번 실행되며, 처음에는 빠른 추정치를 제공하고 데이터가 더 많이 도착하면 더 나은 추정치를 연속적으로 제공합니다. 마지막 단계에서는 월별 게이지 데이터를 사용하여 연구 수준 제품을 만듭니다. 알고리즘에 관한 자세한 내용은 IMERG 기술 문서를 참고하세요.
