The first performance indicator is simply a document detailing the SLA or service level definition. The primary goals of the service level definition should be availability and performance because these are the primary user requirements.
Temperature decreases with elevation. During summer, temperature is strongly controlled by elevation -- cold at the higher reaches of the Alaska and Brooks Ranges, and warmer in the lowlands. How does elevation affect climate? As elevation _________, the average annual temperature __________.
But it is important to remember that density altitude also has a negative effect on performance at low elevation airports when the temperature goes above the standard air value of 15 C at sea level. Remember also that the standard air temperature value decreases with altitude.
