Mapping and Monitoring Algorithm (FIMMA)

The original FIMMA algorithm was based on the scheme described in the paper "Satellite-based Detection of Canadian Boreal Fires: Development and Application of the Algorithm" by Dr. Zhanqing Li, (et al) of the Univ. of Maryland, modified with the addition of a slightly simplier method for nighttime fire detection. This was basically a threshold ...

YOLO Algorithm For Object Detection: A Simple Guide (2021)

Mar 30, 2021· YOLO (“You Only Look Once: Unified Real-Time Object Detection”) is one such real-time Object detection algorithms. It was first described in the seminal 2015 paper by Joseph Redmon et al., where the concept of YOLO was determined and its implementations, ‘Darknet’ was discussed. Over time, there are many improvements made in the YOLO ...

Algorithm Document TOSOMI

The new GOME algorithm TOGOMI [Valks and Van Oss, 2003] is based on the total ozone DOAS (Dif-ferential Optical Absorption Spectroscopy) algorithm developed for the OMI instrument [Veefkind and De Haan, 2001]. With respect to total ozone column retrieval using the DOAS method, the OMI, SCIA-MACHY and GOME instruments are very similar.
