abstract = "The current paper presents a method for mapping summer annual
agriculture (maize and soybean) by analyzing Land Surface
Temperature (LST) time-series derived from the Moderate Resolution
Imaging Spectroradiometer (MODIS). We used Terra and Aqua LST
daytime and nighttime data (M_D11A2) with 8-day temporal and 1km
spatial resolution. The physical basis behind the method is the
heat transfer between soil, plant and atmosphere over time. There
are two approaches, inter-daily and intra-daily LST variation. We
tested daytime and day-night difference time-series, being the
latter more efficient on detecting annual agriculture. Regarding
the satellites, Aqua proves on being more efficient due the
passage hour for daytime. In sense, the couple Difference/Aqua
yielded better results. However, the performance is strongly
dependent on the contiguity of agricultural areas due to the high
thermal mixing susceptibility. Another drawback is the spatial
resolution (1 km) which depending on the situation fails on
detecting low acreage crops. Despite the limitations, the idea
shows potential to be coupled to traditional vegetation indices
based methods for furthering the biophysical meaning and
relationships between vegetation and remote sensing. It also
brings new findings about vegetation thermal behavior throughout
the time..",
