Description: <p><span style="font-size:12px;">The 2024 Campaign expanded the coverage area (69 routes versus 32 in 2020) with a particular focus on Houston's disadvantaged communities; an area where around two million people live. It will also be incorporated into a tree equity analysis to develop a scientific basis to guide tree plantings, prioritizing sites around public community features that have high heat, low tree canopy coverage, and a high rate of tree loss.&nbsp;</span> <span style="font-size:12px;">Additional analysis on the 2024 CAPA heat data with the For Us Tree study area by Community Tabulation Area 2010. The two areas Willowridge and Four Corners are within the For Us Tree project area but they are not Kinder Rice Community Tabulation Areas.</span></p><ul><li><span style="font-size:12px;"><strong>Summary Statistics</strong>: Compute minimum, mean, maximum, and range statistics by census tract for all three modeled temperature layers.</span></li><li><span style="font-size:12px;"><strong>Average Temperature Calculation</strong>: Determine the average temperature across the entire study area for each of the three times, excluding non-disadvantaged areas.</span></li><li><span style="font-size:12px;"><strong>Heat Anomaly Identification (Afternoon)</strong>: Create a temperature anomaly metric for each census tract by comparing the average tract temperature to the overall study area average for each time period.</span></li><li><span style="font-size:12px;"><strong>Percentile Field</strong>: Add a field indicating the percentile rank of each census tract based on the afternoon average temperature.</span></li><li><span style="font-size:12px;"><strong>Morning Heat Comparison</strong>: Compute and add a field representing the maximum morning temperature difference by census tract compared to 80°F.</span></li><li><span style="font-size:12px;"><strong>Daytime Temperature Flux</strong>: Calculate and add a field showing the difference between morning and afternoon temperatures to represent daytime temperature change.</span></li><li><span style="font-size:12px;"><strong>Nighttime Temperature Flux</strong>: Calculate and add a field showing the difference between morning and evening temperatures to represent daytime temperature change</span></li></ul><p style="text-align:center;"><span style="font-size:14px;"><u>Disclaimer</u></span><span style="font-size:12px;">&nbsp;</span></p><p style="text-align:center;"><span style="font-size:12px;">This product is for informational purposes only and may not be suitable for legal, engineering, or surveying purposes.

Copyright Text: HARC, the City of Houston, Harris County Public Health, Harris County Office of County Administration, Harris County Precinct 4, Student Conservation Association, and the National Weather Service (the H3AT Team) joined forces in 2024 to launch the 2024 H3AT Mapping Campaign. Building on the work done in 2020, the H3AT team organized a one-day heat mapping campaign, very similar to the campaign in 2020. The 2024 Campaign Day took place on August 10th. This campaign is being made possible through funding provided by the USDA Forest Service, Urban and Community Forestry Program. This is part of a larger initiative, called ForUsTree: Creating an Inclusive Community Canopy within Houston and Harris County, which aims to increase tree canopy, foster community resilience, and improve access to employment in underserved communities in Houston and Harris County.
