Resumen
Los datos iniciales del satélite Seasat muestran que la temperatura de la superficie del mar se puede medir dentro de los 1,2 grados centígrados utilizando radiómetros de microondas. Esta tecnología produjo el primer mapa de microondas de las temperaturas superficiales del mar del Pacífico.
Área de la Ciencia:
- Oceanografía La oceanografía es la oceanografía.
- La detección remota con sensores.
- Radiometría de microondas y radiometría de microondas
Sus antecedentes:
- Las mediciones precisas de la temperatura de la superficie del mar (SST) son cruciales para comprender la dinámica del océano y el clima.
- Los métodos anteriores para la medición de SST tenían limitaciones en la cobertura global y la precisión.
Objetivo del estudio:
- Para evaluar la capacidad del radiómetro de microondas multicanal de exploración Seasat para medir la temperatura de la superficie del mar.
- Para producir el primer mapa integral de microondas de SST para todo el Océano Pacífico.
Principales métodos:
- Se utilizaron datos del radiómetro de microondas multicanal de exploración Seasat.
- Algoritmos aplicados para procesar datos de microondas para la recuperación de SST.
- Generó un mapa espacial de SST a través de la cuenca del Pacífico.
Principales resultados:

01:13Equipments Used to Measure Body Temperature
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

01:14Temperature 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...

01:14Assessing Body Temperature - Oral
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:

01:27Assessing Body Temperature - Rectal
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

01:19Assessing Body Temperature - Temporal Artery
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.

01:22Thermometers 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...
