What is land surface phenology?
Land surface phenology (LSP) may be defined as the seasonal pattern of variation in vegetated land surfaces observed from remote sensing. LSP dynamics reflect the response of vegetated surfaces of the earth to seasonal and annual changes in the climate and hydrologic cycle.
What is phenological model?
What is a phenology model? Phenology models predict time of events in an organism’s development. Development of many organisms which cannot internally regulate their own temperature, is dependent on temperatures to which they are exposed in the environment.
What is vegetation phenology?
Vegetation phenology is the description of periodic plant life cycle events across the growing seasons. Vegetation phenology with remote sensing is typically monitored by means of time series of vegetation indices.
What is phenology in remote sensing?
Remote sensing phenology—the use of satellites to track phenological events—complements ground observation networks. Satellites provide a unique perspective of the planet and allow for regular, even daily, monitoring of the entire global land surface.
What is phenology data?
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).
How is phenology affected by climate change?
Climate change alters the bioclimatic conditions during the growing period of trees directly, but also indirectly by causing shifts in spring and autumn leaf phenology that lead to changes in the timing and length of the growing period.
What is Phenology data?
What is Phenology in biology?
Phenology is defined as the study of the timing of recurring biological events, the causes of their timing with regard to biotic and abiotic forces, and the interrelation among phases of the same or different species (Leith 1974). From: Global Seagrass Research Methods, 2001.
What is phenology in geography?
Phenology is the study of recurring plant and animal life cycle stages, especially their timing and relationships with the environment. Numerous environmental factors can drive phenological events, but these are primarily atmospheric variables, and in temperate zones predominately related to temperature.
Why is it important to study phenology?
Farmers and gardeners need to know the schedule of plant and insect development to decide when to apply fertilizers and pesticides and when to plant to avoid frosts. Phenology influences the abundance and distribution of organisms, ecosystem services, food webs, and global cycles of water and carbon.
How do you measure phenology?
Measurements. Plant phenology is typically quantified by observing the date of onset and the duration of particular phenophases, which may include both vegetative and reproductive events. Specific phenophase definitions have not been universally adopted across monitoring networks.
Why is measuring phenology important?
Scientists use much more detailed methods of tracking phenological events, which allows them to measure such things as climate change and the long-term sustainability of a given population of plants or animals.
