Spectral diagonal ensemble Kalman filters
Ivan Kasanický, Jan Mandel, Martin Vejmelka
A new type of ensemble Kalman filter is developed, which is based on replacing the sample covariance in the analysis step by its diagonal in a spectral basis. It is proved that thi…
Data Assimilation of Satellite Fire Detection in Coupled Atmosphere-Fire Simulation by WRF-SFIRE
Jan Mandel, Adam K. Kochanski, Martin Vejmelka +1
Currently available satellite active fire detection products from the VIIRS and MODIS instruments on polar-orbiting satellites produce detection squares in arbitrary locations. The…
Data assimilation of dead fuel moisture observations from remote automated weather stations
Martin Vejmelka, Adam K. Kochanski, Jan Mandel
Fuel moisture has a major influence on the behavior of wildland fires and is an important underlying factor in fire risk assessment. We propose a method to assimilate dead fuel moi…
Data assimilation of fuel moisture in WRF-SFIRE
Martin Vejmelka, Adam K. Kochanski, Jan Mandel
Fuel moisture is a major influence on the behavior of wildland fires and an important underlying factor in fire risk. We present a method to assimilate spatially sparse fuel moistu…
Non-linear dependence and teleconnections in climate data: sources, relevance, nonstationarity
Jaroslav Hlinka, David Hartman, Martin Vejmelka +2
Quantification of relations between measured variables of interest by statistical measures of dependence is a common step in analysis of climate data. The term "connectivity" is us…
