Snow persistence across the contiguous U.S.

by u/houndrunner

A map of the contiguous U.S. using a snowflake hex pattern to show snow persistence over a 20-year period. Snow persistence is measured as the snow cover index, or the average fraction of time snow was on the ground from Jan 1 to July 3 from 2001-2020. Snowier places are white with snow, emphasizing the Rocky Mountains and Sierra range in the western U.S., and Maine in the northeast. The majority of the southern half of the country is within a 0-10% snow cover index.

Made using the sf, terra, ggplot2, ggimage, scico, magick, and cowplot packages in R.

U.S. Flow Conditions: August 2022

by u/houndrunner

A tile map of the US with proportional area charts for each state showing the proportion of streamgages by flow levels, categorized using percentile bins. Streamflow level percentiles are calculated using the historic daily record for each gage, and binned to reflect whether flow conditions are wetter or drier than the historical record. For the month of August, the Northeast states faced very dry conditions. The Northwest states also faced dry conditions, along with much of the Midwest. Arizona and New Mexico, along with Louisiana and Missouri, faced flood levels during this month.

The tile map was made in R (see code) using ggplot2 and the geofacet packages. Data are from the USGS National Water Information System, accessed in R using dataRetrieval. See it on twitter

If Rivers Were Mountains

by u/houndrunner

Contiguous U.S. river systems mapped as mountains, using a linemap technique. Inspired by James Cheshire's 'Population Lines' and the linemap package. This was made with R and the USGS small-scale hydrography dataset. See the code: https://github.com/USGS-VIZLAB/idea-blitz/tree/main/river-ridgelines
