# Introduction

The following data were collected at three weather stat ions and one air monitoring station located on the

Morongo Indian Reservation. The weather statio ns include a CS3001 Anemometer/Wind Vane, a CS500

Temperature/RH Probe, an LI200X Pyronometer, a TE525 Rain Gauge, a CS205 Fuel Temperature Stick, and a

CS505-L Fuel Moisture Stick. The air monitoring station includes a 49c Thermo Ozone Analyzer, and Met One

BAM1020 PM2.5 Analyzer, and an RM Young wind assemb ly. This summary was prepared by Jason Mandly,

Environmental Specialist, and James Payne, Environmen tal Supervisor/GIS, with the Morongo Environmental

Protection Department

# Definitions

**Average High (Low): This value takes the average of th e highest (lowest) recorded temperature per day. Units are** 

**in degrees Fahrenheit**

**Fuel Moisture: The percent of the total weight of vegetation that is water** 

**Fuel Temperature: The tempe rature of dry vegetation** 

**Insolation: A measure of energy rece ived from solar radiation. Units**  **are in kilowatts per square meter**

**Max High (Min Low): This value represents the highest (lowest)**  **temperature recorded**

**Ozone: An invisible gas and pollutant at lower levels of the atmosphere. Units are in**  **parts per million (ppm)**

**PM2.5: Particles sized under 2.5 micrograms. A pollu tant. Units are in microg**  **rams per cubic meter.**

**PW: Public Works Weather Station**

**Well 6: Well 6 Weather Station, located in Potrero Canyon** 

**Windrose: A graphic representation of wind direct ion versus another value (wind speed, pollution** 

**concentration, etc.)**

**Wind Speed: Measured in meters per seco nd (m/s). 1 m/s = 2.24 miles per hour** 

**WWTP: Wastewater Treatment Plant Weather Station, located east of the Casino** Date Rainfall Average High Average Low Max High Min Low Total Annual Rainfall
