These are Mann Kendall results showing trends in NH4 mass loadings in NADP's National Trends Network. Only statistically signficant results are shown (pvaule < 0.1). Mass loadings are defined as NH4 * sample volume.

This uses a Mann Kendall trend test to determine potential trends in Calcium concentrations multiplied by sample volume (ie, changes in calcium due to mass, not precipation)

Shows the 2019 median calcium concentrations between June-September across all NADP Sites

Interactive plot that shows NH3 concentrations from WRF-Chem Trajectory Simulations. Trajectories launched starting on June 27
