## EOS Goals & Mission Objectives

***Goals***
**Develop an understanding of the total Earth system, and the effects of natural and human-induced changes on the global environment**
**Expand scientific knowledge of the Earth system using NASA’s unique capabilities from the vantage points of space, aircraft, and in situ platforms**
**Disseminate information about the Earth system**
**Support national and international environmental policy recommendations**
***Mission Objectives***
**Create an integrated scientific observing system that will enable multidisciplinary study of Earth system science**
**Develop a comprehensive data and information system, including a data retrieval and processing system**
**Acquire and assemble a global database emphasizing remote sensing measurements from space over a decade or more**
**Improve predictive models of the Earth system**

## Landsat 7

***Launched April 15, 1999***

***Landsat 7***

## The Limpopo River in Mozambique before and after the flooding from Cyclone Eline
About 700 people were killed and thousands were displaced by this event

**About 700 people were killed and thousands were displaced by this event**

***Flooding in Mozambique***

## Cape  Town & the Western Cape

## Terra

**ASTER**

***Launched December 18, 1999***

**MODIS**

**CERES**

**MISR**

**MOPITT**

***Terra***

## Terra’s Global Perspective

**1-2 day global coverage  in 36 wavelengths from 250 m to 1 km resolution**
**MISR**
**Stereo images at 9 look angles**
**ASTER**
**Hi-resolution, multi-spectral images from 15 m to 90 m resolution, plus stereo**
**MOPITT**
**Global measures of CH****4**** & CO**
**CERES**
**Measures Earth’s shortwave, longwave, and net radiant energy budget**

***Terra’s Global Perspective***

## SAFARI 2000

**Largest single initiative being conducted for Terra validation**
**Airborne measurements**
**NASA ER-2 aircraft - remote sensing with sensors analogous to spaceflight sensors on Terra**
**University of Washington CV-580 - in situ microphysics, atmospheric chemistry, spectral and angular radiation, aerosol optical thickness**
**South African Weather Bureau (SAWB) Aerocommanders - cloud microphysics, carbon monoxide, cloud condensation nuclei**
**Surface networks**
**SAVE ground validation sites (Skukuza, South Africa; Mongu, Zambia)**
**AERONET - global network of over 60 sun/sky radiometers, some of which are seasonal and some of which are permanent**
**Fire emission/temperature towers for characterizing carbon efficiencies (burning & smoldering phase)**
**Full scientific partnership between the United States and South African scientists**

## Access and training on use of Earth observing platforms
Data on the environment (water quality, air quality, land cover & land use change, ocean conditions, long term weather prediction) available free of charge
Only useful to regional government and science establishment if trained human resources are able to fully take advantage of these data
Development of academic links between SADC member states and US government and academic institutions, including training of students in both regions
Mirror data centers are being set up in the US and in RSA (Wits) to allow free access and training on use of these new observations
Satellite observations will continue for the next 15 years, even though SAFARI 2000 is being conducted for intensive periods over 3 years
Long-term environmental monitoring
Enables government to do periodic assessments of changes in land use and air quality at nominal cost
