Measuring Snow - Old Classic

Introduction

This tutorial provides a comprehensive guide on how to properly measure snow, based on a classic instructional video by the National Weather Service and Colorado State University. Accurate snow measurement is crucial for weather reporting, research, and public safety. This guide will outline the essential steps and best practices for measuring snow effectively.

Step 1: Gather Necessary Tools

Before measuring snow, ensure you have the right tools at hand.

• Snow Measuring Stick: A marked stick, preferably at least 3 feet long.
• Ruler: A standard ruler can be used if a measuring stick is not available.
• Flat Surface: Identify a level area away from obstructions (trees, buildings) to avoid discrepancies in measurements.
• Notebook: For recording measurements and conditions.

Step 2: Choose the Right Location

Select an appropriate site for snow measurement. Consider the following:

• Open Area: Measure in an unobstructed space to get a true representation of the snowfall.
• Avoid Drifts: Snow drifts can cause uneven accumulation. Choose a spot where the snow is evenly settled.
• Consistency: If measuring over multiple days, use the same location each time for consistency.

Step 3: Measure the Snow Depth

Follow these steps to accurately measure snow depth:

1. Insert the Measuring Stick: Place the stick vertically into the snow until it reaches the ground.
2. Check the Measurement: Read the depth where the snow surface meets the stick.
3. Record the Measurement: Write down the depth in inches or centimeters.

Step 4: Measure Snow Water Equivalent

Understanding the water content in the snow is important for various applications. Here’s how to measure it:

1. Collect a Snow Sample: Take a container (like a coffee can) and fill it with snow.
2. Melt the Snow: Allow the snow to melt completely.
3. Measure the Water: Use a measuring cup to determine how much water is produced. This helps assess the snow's water equivalent.

Step 5: Document Conditions

Record additional information along with your measurements. Important details include:

• Temperature: Note the air temperature at the time of measurement.
• Snow Density: If possible, estimate whether the snow is wet or dry, as this affects its water content.
• Date and Time: Always record when the measurement was taken for accuracy in reporting.

Conclusion

Measuring snow accurately requires the right tools, a proper location, and attention to detail. By following these steps, you can contribute valuable data for weather analysis and reporting. Remember to measure consistently and document conditions to enhance the quality of your observations. For further learning, consider participating in a snow measurement program, such as CoCoRaHS, to share your data with a broader community.
