Digital Technology

Remote realizing – info collected by aerial picture taking and satellite tv imagery. Possui – Approach to satellites & receivers to plot position. GPS – Global Positioning Program – approach to satellites & receivers to plot location. GIS – Geographic Info System, -- System to control & screen spatial data. Electrical lines, gas lines, etc .

Remote Sensing

Aerial Digital photography

Discern space patterns

Source Inventory

Crisis Management

Sun-Synchronous Satellites: adjust settings to highlight certain things LANDSAT

AVHRR

Geostationary Geostationary satellites

GEOES (Weather)

GPS

Global Positioning Program

24 geostationary satellites orbit the planet every 12 hours

Satellites transmit pseudo random code

Time of sign to receiver gives length

Triangulation gives position

GIS

Geographic Information System

System to get storing, studying and exploit spatially referenced data Info consists of layers of one variable such as: vegetation, landforms, or perhaps soils Levels can be overlaid/combined for analysis or display

App include: reference management, organizing, hazard assessment, etc .

Earth-Sun romance

Most Physical Processes in the world powered by incoming rays from Sunlight. Earth-Sun Romance Complex – Depends on:

Latitude

Placement of Sun in Sky

Time of Year

Globe's Rotation/Axial Point

Our Place in Space

Big-Bang Theory

Milky Way Galaxy

Our Solar-system

Shape of our planet

Oblate Spheroid

Variation in Sun Perspective by Lat.

Subsolar Level

The Sun

About 4. 6th Billion Years Old

Average Celebrity, Nothing special

100 occasions diameter of Earth

Power most natural operations on Earth

eight. 3 min. for sun's energy to achieve Earth

Solid Magnetic Fields/Sunspots

The Earth follows an oblong orbit around the Sun with its nearest point by Perihelion and its particular farthest point at aphelion. The Globe's Rotation & Axial Tilt

The Globe's Rotation about its Axis Counterclockwise Rotation around North Pole Moon's orbit throughout the earth is usually counterclockwise

Global Time

24 Time Zones

Perfect Meridian

International Particular date Line

The Seasons

Earth's lean 23. 5* from verticle with respect to Ecliptic

Angle and Orientation frequent in Orbit

Tilt & revolution combine to cause seasons Upper & The southern part of Hemispheres alternative direct the radiation from the Sunshine Subsolar Level migrates among 23. 5*N & 3. 5*S The Earth's orbit and tilt combine to develop the seasons. Solstice and Equinox

Spring Equinox (March 20-12)

Subsolar Level – Collar

Summer Solstice (June 20-21)

Subsolar Level – Tropic of Cancers – 23. 5* In

Fall Equinox (Sept 22-23)

Subsolar Level – Equator

Winter Solstice (Dec 21-22)

Subsolar Point – Tropic of Capricorn – 3. 5* S

Earth-Sun Angles on Earth

The Global Strength System

The Electromagnetic Spectrum and Solar power

Microwaves, tv's, info reddish colored lights, cell phones, etc

Composition from the Atmosphere

The Flow of Radiation that is known

The Global The radiation Budget

The Electromagnetic Variety

Radiation – Electromagnetic (EM) energy sent as a influx Wavelength

Amplitude

The entire wavelength range of NA energy

Gamma rays -> X-rays-> ultra-violet-> infrared->

Shortwave Radiation

Emitted by " hot” objects, i. elizabeth. the Sun, 60000C Surface temp Gamma light, X-rays, Ultraviolet, Visible light and Near-infrared Hot objects emit far more radiation than cooler objects

Longwave Radiation

Provided by " cool” items, i. e. those on Earth's surface area, even things hot to touch, or also hot to touch Avg. temp of Earths surface 16*C

Heat infrared wavelengths

Earth's Ambiance

Medium solar power passes through

Unique in solar system – provides 0 2 and CO 2 for breathing and the natural photosynthesis Shields The planet from UV radiation

Runs like a water with power and eddies
