GES DISC DAAC Data Guide: Rain Gauge Instrument 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Explanation: The Dataset or Sensor Guide Document you are accessing is no longer actively maintained.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 rain gauge is an instrument that collects and measures the amount of rainfall, expressed in millimeters of depth.

Table of Contents:

1. Sensor/Instrument Overview:

Sensor/Instrument Long Name, Sensor/Instrument Acronym:

Rain gauge.

Sensor/Instrument Introduction:

A rain gauge is an instrument designed to measure the amount of rainfall that has fallen, expressed in millimeters of depth. The data collected from the rain gauge network is compiled at a meteorological station.

Sensor/Instrument Mission Objectives:

The objective of a rain gauge instrument is to collect measurements of precipitation in the area where the gauge is located.

Key Variables:

The primary parameter for rain gauges is precipitation.

Scanning or Data Collection Concept/Principles of Operation:

Rain gauge data collection methods vary. The collection of precipitation measurement occurs on a periodic basis.

2. Sensor/Instrument Layout, Design, and Measurement Geometry:

List of Sensors:

Rain gauges.

Sensor Description:

A rain gauge is an instrument that measures the amount of precipitation in the location of the instrument since the last collection was made from the rain gauge. Data are compiled from terrestrial precipitation gauge measurements in their traditional setting which can include gauges elevated above the ground and possibly with a gauge shields.

3. Manufacturer of Sensor/Instrument:

Manufacturers of rain gauges vary.

Ground station

A site located on the surface of the earth that collects various meteorological parameters from a variety of instruments.

Rain gauge

An instrument that measures the amount of precipitation in the location of the instrument since the last collection was made from the rain gauge.
