GES DISC DAAC Data Guide:
Ship Platform Document

Message Alert Notification THIS DOCUMENT IS AVAILABLE ON THE GES DISC WEB SITE FOR HISTORICAL INFORMATION PURPOSES ONLY. Information provided in this document may not be accurate. We recommend checking other sources related to these data or sensors to acquire reliable and updated information.

Explanation: The Dataset or Sensor Guide Document you are accessing is no longer actively maintained. The Dataset Guide Documents were created for earlier versions of the NASA EOSDIS system. The content of these documents, particularly with regard to characteristics of the data or technical descriptions of a sensor, is likely still accurate. However, information such as contact names, phone numbers, mailing addresses, email addresses, software programs, system requirements, and data access procedures may no longer be accurate. We therefore recommend searching for updated information from other sites to insure that reliable and current information is obtained.


Summary:

A ship is any large seagoing vessel. Meteorological data can be collected from a variety of ships, including reseach vessels, commerical vessels and military vessels. The ships can provide rain gauge data that supports the need for a global precipitation climatology over the ocean. The primary source for a global precipitation climatology data set is the qualitative shipboard observations collected. The qualitative precipitation estimates from shipboard measurements are recognized as being fraught with uncertainties since even the visual classification of precipitation intensity and character by shipboard weather observers is a highly subjective task. However, these shipboard measurements still represent the historical estimates of oceanic precipitation.

Table of Contents:

1. Source/Platform or Data Collection Environment Overview:

Source/Platform or Data Collection Environment Long Name, Source/Platform Acronym:

Ship.

Source/Platform Introduction:

Collection Environment:

Oceans.

Source/Platform Program Management:

The program management for a ship varies depending on the particular study for which the data is being collected or the commerical venture the ship is supporting.

Source/Platform Mission Objectives:

This information is not available at this time.

Source/Platform Parameters:

The platform parameters could vary greatly among all the ships that are used to collect data. Some vessels used for data collection serve the dual purposes since they may be commerical ships sailing along trade routes and collecting data during that passage.

Coverage Information:

The coverage of a ship is potentially the global oceans. However, ships can not sail into polar regions that are covered by ice so the coverage will vary by season. The coverage of a ship is also dependent on the mission of that particular vessel. A commerical vessel may travel only along established trade routes.

Attitude Characteristics:

This information is not applicable to a ship.

Data Collection System:

The data collection system from the ship will vary depending upon the mission of the ship and the study. The data could be transmitted to a meteorological station via a computer downlink or the data could be transfered via a hardcopy of the measurements.

Communication Links:

This information is not available at this time.

List of Sensors/Instruments:

Instruments include rain gauges, barometers and navigational tools.

2. Ground Segment Information:

Tracking and Control:

This information is not applicable to a ship.

Data Acquisition and Processing:

After the data is collected aboard the ships, it can be transferred to a meteorological station for entry into a measurements database.

Latitude Crossing Times:

This information is not applicable to a ship.

3. References:

No references are available at this time.

4. Glossary of Terms:

See the EOSDIS Glossary for a more general listing of terms related to the Earth Observing System project.

5. List of Acronyms:

See the EOSDIS Acronyms for a more general listing of terms related to the Earth Observing System project.
