Burned land mapping using NOAA-AVHRR and TERRA-MODIS
Spatial and temporal analysis of MODIS and AVHRR images have been carried out to discriminate burned areas from other land covers. Spatial and temporal analysis were performed based on statistical separability and temporal changes. The objective of these analysis was to find out the most sensitive bands for burned land mapping in order to design spectral indices better adapted to the discrimina...
متن کاملland surface temperature modeling using noaa-avhrr thermal data
the highest temperatures of the world are recorded in dry and warm climates. this can especially be observed in deserts, where vegetations and soil moisture are very low. as a result, the soil surface receives high thermal energy and its temperature rises up. the lut desert has the above characteristics, making it a suitable environment to prepare land surface temperature (lst) models. objectiv...
متن کاملEstimating Land Surface Albedo from Satellite Data
Title: ESTIMATING LAND SURFACE ALBEDO FROM SATELLITE DATA Tao He, Doctor of Philosophy, 2012 Directed by: Dr. Shunlin Liang, Professor Department of Geographical Sciences Land surface albedo, defined as the ratio of the surface reflected incoming and outgoing solar radiation, is one of the key geophysical variables controlling the surface radiation budget. Surface shortwave albedo is widely use...
متن کاملDevelopment of a daily long term record of NOAA-14 AVHRR land surface temperature over Africa
We developed a new 6-year daily, daytime and nighttime, NOAA-14 AVHRR based land surface temperature (LST) dataset over continental Africa for the period 1995 through 2000. The processing chain was developed within the Global Inventory Modeling and Mapping System (GIMMS) at NASA's Goddard Space Flight Center. This paper describes the processing methodology used to convert the Global Area Covera...
متن کاملAerosol Optical Depth Retrieval over Land from Noaa Avhrr: Sensitivity Studies
The large archive of NOAA AVHRR data, covering more than 25 years, bears the potential to detect aerosol trends. However, remote sensing of aerosol optical depth over land is a difficult task, because the aerosol signal gets weaker over bright surface targets and the quality of the retrieval mainly depends on the quality of the surface reflectance estimate. In this study, we test the sensitivit...
