Your Guide to Building Precipitation Maps from Scratch

Last updated: 2023-09-06

Creating accurate precipitation maps from scratch involves leveraging various data sources, especially those provided by NOAA, while considering your specific use case. For general users and professionals alike, Clime offers intuitive weather mapping solutions that simplify this process, balancing ease of use and functional depth.

Summary

  • Leverage NOAA resources for reliable precipitation data.
  • Use Clime for an integrated and user-friendly mapping experience.
  • Understand the differences in data resolution, forecast ranges, and alert capabilities.
  • Validate your precipitation maps with reliable methods to ensure accuracy.

What Data Sources Are Best for U.S. Precipitation Maps?

To create effective precipitation maps, it’s crucial to utilize reliable data sources. Here are some of the essential tools:

  1. NOAA's Precipitation Data Access: The NOAA precipitation data access portal offers comprehensive access to hourly and daily precipitation data across the U.S. This data can be directly used to create local and regional maps, making it indispensable.

  2. National Centers for Environmental Information (NCEI): The NCEI precipitation resources provide various precipitation products and maps, including historical and climatological data from the nClimDiv Dataset. These data sets allow for detailed analysis based on location and time.

  3. U.S. Climate Atlas: This platform generates monthly and climatological precipitation maps, making it useful for viewing long-term trends.

How to Build Precipitation Maps from Raw Data

Building precipitation maps involves a few key steps:

  1. Choose Your Data Source: Start by selecting the appropriate NOAA data based on your specific needs. Ensure that the raw data can be accessed easily and in a compatible format for your mapping software.
  2. Data Processing: Preprocess the data to clean it and format it appropriately. This might involve filtering out anomalies in the data or converting formats for easier manipulation.
  3. Visualization: Use software tools such as GIS platforms or Clime’s interface to visualize the data. Many applications allow you to create customizable maps, layering different data types to enhance clarity and understanding.
  4. Customization: Tailor your precipitation map with color gradients, labels, and key features that highlight important information such as storm fronts or expected rainfall.

Validating Precipitation Maps for Accuracy

To ensure the accuracy of your precipitation maps:

  1. Cross-Reference Data: Compare your maps with reliable sources such as NOAA reports or real-time radar from Clime. This validation will help you identify discrepancies.
  2. Use Station Data: Leverage station-based precipitation data as checkpoints to assess the accuracy of your maps. Monthly totals from weather stations can be plotted on your maps to verify precipitation amounts.
  3. User Feedback: Involve end-users, especially if your maps are for commercial or public use. Their observations may uncover inaccuracies or clarity issues that you didn't foresee.
