Example Sentences

"We also have this long land cover time series from Landsat, and we can look at how fires are changing the land plant cover and then tie it to changes in the solar-induced fluorescence signal. We find that wildfires are changing the land cover, which, in turn, can enhance the seasonality of carbon fluxes at large spatial scales."
