El monitoreo preciso de las tendencias de la temperatura global desde satélites
Resumen
La radiometría pasiva de microondas por satélite ofrece datos precisos de la temperatura atmosférica. El análisis de 10 años de datos (1979-1988) mostró una variabilidad significativa de la temperatura, pero no una clara tendencia al calentamiento del efecto invernadero.
Área de la Ciencia:
- Ciencias de la atmósfera ciencia atmosférica.
- Ciencias del clima ciencia del clima.
- La teledetección es la sensorización remota.
Sus antecedentes:
- Los datos precisos de la temperatura atmosférica global son cruciales para la investigación del cambio climático.
- La radiometría pasiva de microondas por satélite ofrece una precisión superior en comparación con los escasos termómetros terrestres.
- Comprender la variabilidad de la temperatura atmosférica es clave para detectar las tendencias climáticas.
Objetivo del estudio:
- Para analizar los cambios de temperatura de la atmósfera inferior utilizando mediciones satelitales.
- Para evaluar la precisión y la variabilidad de los datos de temperatura global.
- Para identificar cualquier tendencia discernible en la temperatura atmosférica durante una década.
Principales métodos:
- Utilizó datos de radiometría pasiva de microondas de los satélites.
- Se analizaron 10 años de mediciones de 1979 a 1988.
- Precisión de temperatura mensual calculada y variabilidad y tendencias identificadas.
Principales resultados:
- Logró una precisión mensual de 0.01 grados C.
- Se observó una variabilidad significativa de la temperatura en diferentes escalas de tiempo.

Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
Errors in Global Positioning System
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...
Types of Global Positioning System Surveys
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...
Thermometers and Temperature Scales
Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
As many physical properties depend on temperature, the variety of thermometers is...
