GHRC data recipes

Tutorials or step-by-step instructions have been developed by GHRC staff to help you learn to discover, visualize and use new data, information, software and techniques. These recipes cover a variety of datasets and processing languages/software.

Field Campaign Explorer (FCX)


Field Campaign Explorer (FCX)

The Field Campaign eXplorer (FCX) addresses challenges inherent with utilizing diverse field campaign datasets to improve data management and discoverability to enable scientists to rapidly collect, visualize, and analyze the data in a common framework.
FCX Tool

TCPF tool



The Level 1 Tropical Rainfall Measuring Mission (TRMM) Tropical Cyclone Precipitation Feature (TCPF) Database 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

NASA Earthdata Search

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.

EOSDIS Worldview

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.


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.


Panoply is a cross-platform application that plots geo-gridded and other arrays from netCDF, HDF, GRIB, and other datasets.


IDL (Interactive data Language) is an analysis and visualization tool.

Hierarchical Data Format

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.

Cyclone Center

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.
