You can search through the dataset holdings at the GHRC using HyDRO, the Hydrologic data Search, Retrieval, and Order system. HyDRO can provide you with a list of GHRC datasets specific to your requirements. You can then browse through the online information for each dataset, download the online datasets, or place an order for any offline datasets.
The Algorithm Development and Mining System (ADaM) developed by the Information Technology and Systems Center at the University of Alabama in Huntsville is used to apply data mining technologies to remote sensed and other scientific data. ADaM provides a toolkit of pattern recognition, image processing, optimization, and association rule mining capabilities. Using common scripting languages such as Python, Perl, and shell, ADaM components can be used to solve complex data analysis problems.
Globally Leveraged Integrated Data Explorer for Research (GLIDER) is a freely available and easy-to-use tool to visualize, analyze, and mine satellite imagery. It is a powerful tool that combines existing mining and image processing services to enable researchers to fully exploit the large volumes of NASA satellite imagery data needed for scientific research.
GHRC Satellite Coincidence Search Engine
The Coincidence Search Engine may be used to search for times when up to four satellites were over or within the same geographic area simultaneously. Searches may be constrained by time, geographic area, and/or distance between the satellites. The output consists of a sequence of text lines listing the date, time, satellite name, and latitude and longitude.
GHRC public services
GHRC offers a selected group of public service interfaces to its HyDRO, Coincidence Search Engine, Satellite Services, and Storms utilities. The Public Services page contains details such as interface descriptions and service addresses.
GHRC recently acquired the Level 1 Tropical Rainfall Measuring Mission (TRMM) Tropical Cyclone Precipitation Feature (TCPF) Database, which provides TRMM-based tropical cyclone swath data. The TCPF Level 1 dataset marks the shift in GHRC's direction towards the new focus of hazardous weather. This tool can be used to query the TCPF database and both visualize and download data.
External Tools & Technologies
Earthdata is a tool provided by NASA for the purpose of accessing, searching, ordering, and discovering data housed in the ECHO metadata collection. Earthdata also has a tutorial video available.
The Hierarchical Data Format (HDF) is a popular data format that can be used to store a variety of data "objects", such as arrays, annotations, and images. The HDF libraries, available for FORTRAN and C programmers, have been ported to a variety of platforms.
HDF is the prescribed format for standard data products that are derived from EOS missions. HDF-EOS (Hierarchical Data Format - Earth Observing System) is a self-describing file format for transfer of various types of data between different machines based upon HDF. HDF-EOS is a standard format to store data collected from EOS satellites: Terra, Aqua and Aura.
NetCDF (network Common Data Form) is an interface for array-oriented data access and a library that provides an implementation of the interface.
Worldview shows the entire Earth as it looks "right now" - or at least as it has looked within the past few hours. Worldview supports time-critical application areas such as wildfire management, air quality measurements, and weather forecasting.
IDL (Interactive data Language) is a analysis and visualization tool.
Esri's ArcGIS is a geographic information system (GIS) for working with maps and geographic information. It is used for: creating and using maps; compiling geographic data; analyzing mapped information; sharing and discovering geographic information; using maps and geographic information in a range of applications; and managing geographic information in a database.
Cyclone Center is a Zooinverse citizen science project that relies on volunteers to help researchers categorize tropical cyclone imagery according to system strength, intensity, and other factors. The project uses the Dvorak technique to classify tropical cyclones that have formed since the 1970s.
