ABSTRACT
Based on the time scales that prevail in the atmosphere, the atmospheric boundary layer (BL) is divided into microscale and partly to meso- and gamma-scales. Scaling is the basic processes for measuring the atmospheric process. This scaling of atmosphere mainly helps in atmospheric prediction. This entire layer had a relationship with micrometeorology and carbon fluxes prevailing inside and outside the crop growth and canopy. The factors that affect the microclimate are landform, vegetation, water bodies, soil, and artificial structures like buildings, trees etc. Crops in relationship with the BLs include surface and internal BL in micrometeorology. The parameters which would favor crop production are relative humidity, canopy temperature, soil temperature, photosynthetically active radiation, and leaf gas exchange parameters. Each parameter has specific instrument for measuring apart from using the sensors. Every single factor has a wider role, for example, a root growth is only concerned with soil temperature and shoots growth fretful by canopy temperature and relative humidity. Satellite-based crop monitoring for
pest and diseases uses methane assessment that is done by change in carbon and nitrogen flux in inside and outside the plant canopy. These applications are helpful in crop monitoring. Each factor of BL in micrometeorology had a greater impact in satellite and land-based observations of methane.
