An Introduction to the Drought Monitor

Mini-lysimeters to monitor transpiration and control drought stress: system design and unique applications

Methods for the precise control of drought stress have been a holy grail of plant biology research. Here we describe a five-container growth chamber system and a 16-container greenhouse system, each of which uses load cells to monitor and control the mass of a soil/plant system. The calibration and signal conditioning necessary to quantify transpiration over 10 minute intervals is described. Ev...

A Combined Approach with Smos and Modis to Monitor Agricultural Drought

A synergistic fusion of the Soil Moisture and Ocean Salinity (SMOS) L2 soil moisture with the Moderate Resolution Imaging Spectroradiometer (MODIS)-derived land surface temperature (LST) and several water/vegetation indices for agricultural drought monitoring was tested. The rationale of the calculation is based on the inverse relationship between LST and vegetation condition, related in turn w...

applying first-order markov chains and spi drought index to monitor and forecast drought in west azerbaijan province of iran

in this paper by using the data related to the monthly precipitation of 13 stations situated in west azerbaijan province of iran in a time period of 34 years, monitoring and forecasting the probability of a drought occurrence is evaluated in next coming months. in this process, first the monthly precipitation amounts for each rainfall station are used in order to calculate the standardized prec...

The topic of data warehousing encompasses architec-tures, algorithms, and tools for bringing together selected data from multiple databases or other information sources into a single repository, called a data warehouse , suitable for direct querying or analysis. In recent years data warehousing has become a prominent buz-zword in the database industry, but attention from the database research c...
