이 갭이 채워진 Tasseled Cap Brightness (TCB) 데이터 세트는 Lobser 및 Cohen (2007)에 정의된 tasseled-cap 방정식을 MODIS BRDF 보정 이미지 (MCD43B4)에 적용하여 생성되었습니다. 결과 데이터는 Weiss et al. (2014)에 설명된 접근 방식을 사용하여 갭을 채워 구름 덮개와 같은 요인으로 인해 누락된 데이터를 제거했습니다. 데이터를 갭 필링한 후 유효한 값을 보장하기 위해 [-1, 2] 의 임계값으로 클리핑했습니다.
그런 다음 갭이 채워진 8일 간격의 ~1km 출력이 시간별로 집계되어 월별 및 연간 제품이 생성됩니다.
