Metadata for Climate Research Unit Time Series (CRU TS) 2.1

16 May 2012 | Downloads | Contributor(s): Lan Zhao

The CRU TS 2.1 data-set comprises 1224 monthly grids of observed climate, for the period 1901-2002, and covering the global land surface at 0.5 degree resolution. There are nine climate variables available: daily mean, minimum and maximum temperature, diurnal temperature range, precipitation, wet...

Metadata for Harvested Area and Yields of 175 crops (M3-Crops Data)

15 May 2012 | Downloads | Contributor(s): Jake R Carlson

This data collection is composed of land use data sets, generated by combining national, state, and county level census statistics along with a global data set of croplands from countries around the world for the year 2000. The resulting land use data sets depict circa the year 2000 the...

Metadata for Indiana Stream Flow Data

15 May 2012 | Downloads | Contributor(s): Jake R Carlson

The United States Geological Survey (USGS) daily streamflow dataset is the source of this dataset. Streamflow data are subjected to human interference, and therefore data contain both natural and regulated flows. This practice does not cause serious problems in flood frequency analysis (flows are...

Metadata for Historical Averages of Precipitation and Temperature Data

15 May 2012 | Downloads | Contributor(s): Jake R Carlson

This dataset is composed of plots of historical time series of average precipitation (measured in inches) and temperature (measured in fahrenheit degrees) data with five year tendencies for each climate division (CD) within Illinois, Indiana, Kentucky, Michigan, Ohio, and Wisconsin. Data are...

Metadata for Indiana Hourly Precipitation Data (NCDC)

15 May 2012 | Downloads | Contributor(s): Jake R Carlson

This dataset contains hourly precipitation data from 144 COOP raingagues located in Indiana (NCDC TD3240 dataset). The main purpose of this dataset is to provide for at-site rainfall frequency analysis. Several data processing manners were taken:(1) For nearby stations with non-overlapping...

A seasonal-scale climatological analysis correlating spring tornadic activity with antecedent fall–winter drought in the southeastern United States

14 Jun 2011 | Publications | Contributor(s): Dev Niyogi

Using rain gauge and satellite-based rainfall climatologies and the NOAA Storm PredictionCenter tornado database (1952–2007), this study found a statistically significant tendency forfall–winter drought conditions to be correlated with below-normal tornado days the followingspring in north...

A copula-based joint deficit index for droughts

31 Mar 2010 | Publications | Contributor(s): Rao S Govindaraju

Current drought information is based on indices that do not capture the joint behaviors of hydrologic variables. To address this limitation, the potential of copulas in characterizing droughts from multiplevariables is explored in this study. Starting from the standardized index (SI) algorithm, a...

A spatio-temporal drought analysis for the Midwestern US

15 Jun 2009 | Publications | Contributor(s): Rao S Govindaraju, Dev Niyogi

Droughts are prolonged abnormalities of moisture deficits that vary widely across temporal and spatial scales. Many hydrometeorologic variables are used to monitor the status of a drought. However, because of the dependence structure between all affecting variables under various temporal windows,...
