(Pre-requisite: AP 140)

Objective
  To teach the use of satellite images for agro-meteorological purposes.

Theory

UNIT I
  Scope and importance of  agrometeorology from space, types of  meteorological satellites – Geostationary and Polar orbiting.

UNIT II
  International satellite systems and their payloads – NOAA, LANDSAT, SPOT, TERRA and AQUA, DMSP, METEOSAT, GOES, TRMM etc., National satellite systems and their payloads – INSAT, IRS, MEGHA-TROPIQUES, RISAT etc., Agromet parameter’s requirements and satellite data products available.

UNIT III
  Retrieval of cloud type and structure in visible and infrared regions, estimation of rainfall by visible, infrared and passive and active microwave techniques.

UNIT IV
  Retrieval of land surface emissivity and temperature – single channel and split window algorithms, components of surface radiation balance – global radiation, surface albedo and outgoing long wave radiation, estimation of latent heat flux (ET), sensible heat and roughness parameter.

UNIT V
  Retrieval of surface soil moisture by thermal and passive microwave, retrieval of crop biophysical parameters by empirical and physical techniques.

UNIT VI
  Vegetation phenology and dynamics, crop yield modeling, linking Simulation models and remote sensing, crop growth monitoring system

UNIT VII
  Drought monitoring, assessment and management, modeling net primar y productivity of agroecosystems, agroecological zoning using remote sensing and GIS, remote sensing of  air pollutants and green house gases.
