Environmental Data Collections
PTO Satellite Dataset
Provided by Purdue Terrestrial Observatory (PTO), the PTO image data sets currently include data from the GIVSSR sensor on the GOES-12 (also called GOES-East) satellite. These data are collected every 15 to 30 minutes covering different portions or sectors of the earth disk. A full disk scan sector is obtained every 3 hours. The current data products published online include the most recent JPEG-formatted images for the eastern United States and images for the continental United States.
LARS Dataset
Provided by Laboratory for Applications of Remote Sensing (LARS) at Purdue University, the LARS image data collection includes multi-spectral (3 to 15 or so wavelength bands) and hyper-spectral (dozens to hundreds of wavelength bands) image data that are being used for education and research purposes. Most of the image data are for locations in the State of Indiana, dated from 1972 to 2004. The data have been collected by satellite-borne and aircraft-borne sensors. Each band of data in a data set represents the energy received by the sensor that is within the wavelength range of that band. Different sensors cover different portions of the optical spectrum. The primary data formats are ERDAS LAN, Leica Geosystems Imagine, GeoTIFF, and HDF. In addition, some are in LARSYS MIST format.
NWS (National Weather Service) Doppler Radar Data
Purdue University is one of the country's four top-level distributors of high-resolution radar data from the national network of Next Generation Radar (NEXRAD). The NEXRAD Radar system comprises 159 Weather Surveillance Radar-1988 Doppler (WSR-88D) sites across the United States and in selected overseas locations. Using the Unidata Local Data Manager (LDM) technology, NWS data are collected and redistributed in real time. It is composed of Level II and III data. Level II data are in three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. These quantities are further processed to generate numerous meteorological analysis products known as Level III data.
Climate Modeling dataset
This dataset is provided by Professor Matt Huber's research group in the Department of Earth and Atmospheric Sciences at Purdue University. The data are output from the Community Climate System Model (CCSM) to simulate global climate changes. It consists of four dynamic geophysical models simulating the atmosphere, ocean, land surface and sear-ice, and one central coupler component. It facilitates fundamental research on the earth's past, present, and future climate states. This set of data is in NetCDF file format.
