## Summary
A weather satellite is an artificial satellite specifically designed to monitor Earth's weather and climate from orbit. These satellites provide critical data for weather forecasting, climate research, and environmental monitoring. They are a specialized type of Earth observation and research satellite.

## Key Facts
- Weather satellites are classified as both Earth observation satellites and research satellites
- The first weather satellite was launched in 1960 as part of the TIROS program
- Major weather satellite programs include TIROS, Nimbus, Geostationary Operational Environmental Satellite (GOES), and Meteosat
- Weather satellites operate in various orbits including geostationary and polar orbits
- The Nimbus program was a second-generation U.S. robotic spacecraft series with 15 related entries
- Television Infrared Observation Satellite (TIROS) was a series of American weather satellites with 16 related entries
- Modern weather satellites can monitor atmospheric conditions, cloud patterns, ocean temperatures, and other meteorological phenomena
- Weather satellites are used by meteorological organizations worldwide for weather prediction and climate monitoring

## FAQs
### Q: What is the main purpose of a weather satellite?
A: A weather satellite is designed to monitor Earth's weather and climate from orbit, providing critical data for weather forecasting, climate research, and environmental monitoring. These satellites observe atmospheric conditions, cloud patterns, and other meteorological phenomena.

### Q: How do weather satellites differ from other satellites?
A: Weather satellites are specialized Earth observation satellites specifically designed for meteorological purposes, while other satellites may serve different functions like communications, navigation, or scientific research. They carry specific sensors and instruments optimized for atmospheric and climate monitoring.

### Q: What types of orbits do weather satellites use?
A: Weather satellites operate in various orbits including geostationary orbit (remaining fixed over one location) and polar orbit (passing over Earth's poles). Geostationary satellites provide continuous monitoring of specific regions, while polar-orbiting satellites provide global coverage.

## Why It Matters
Weather satellites are essential tools for modern meteorology and climate science, providing the continuous, global observations necessary for accurate weather forecasting and climate monitoring. They enable early warning systems for severe weather events like hurricanes, tornadoes, and floods, potentially saving thousands of lives and billions of dollars in property damage. These satellites also play a crucial role in understanding long-term climate patterns and changes, supporting research on global warming, ozone depletion, and other environmental issues. Without weather satellites, our ability to predict weather patterns, track storms, and understand Earth's climate system would be severely limited, making them indispensable for both public safety and scientific advancement.

## Notable For
- First generation of weather satellites, beginning with the 1960 TIROS launch
- Continuous global coverage capability through geostationary and polar orbiting systems
- Multi-national programs including U.S., European, Russian, Chinese, Japanese, and South Korean systems
- Integration with numerical weather prediction models for improved forecasting accuracy
- Long-term climate data collection spanning decades for climate change research

## Body
### Classification and Types
Weather satellites are classified as both Earth observation satellites and research satellites, reflecting their dual role in monitoring atmospheric conditions and supporting scientific research. They belong to various satellite families and programs including TIROS, Nimbus, GOES, Meteosat, Fengyun, Himawari, and Meteor series.

### Operational Characteristics
Weather satellites operate in different orbital configurations to achieve specific monitoring objectives. Geostationary satellites remain fixed over one location at approximately 36,000 km altitude, providing continuous monitoring of specific regions. Polar-orbiting satellites travel north-south paths, providing global coverage and closer proximity to Earth's surface for higher resolution observations.

### Sensor Technology
Weather satellites carry specialized sensors including visible light cameras, infrared detectors, and microwave radiometers. These instruments can detect cloud formations, measure atmospheric temperatures, monitor ocean surface temperatures, track atmospheric moisture, and observe other meteorological parameters essential for weather forecasting and climate research.

### International Programs
Multiple countries operate weather satellite programs including the United States (GOES, POES, JPSS), Europe (Meteosat, MetOp), Russia (Meteor, Arktika), China (Fengyun), Japan (Himawari), and South Korea (GEO-KOMPSAT-2). These programs often involve international cooperation and data sharing agreements.

### Applications
Weather satellites support numerous applications including short-term weather forecasting, severe weather warnings, tropical storm tracking, agricultural planning, aviation safety, maritime operations, and long-term climate monitoring. They provide data essential for numerical weather prediction models and support research in atmospheric science, oceanography, and environmental studies.
