WSpd: average wind speed measured in meters per second (m/s)
MaxWSpd: max wind speed measured in meters per second (m/s)
MaxWSpdT: time of max wind speed measurement (hh:mm)
Wdir: average wind direction measured in degrees (no correction for magnetic declination).
SDWDir: wind direction standard deviation (sd)
TotPAR: total photosynthetically active radiation measured in millimoles per square meter (total flux integrated over each 15 minute logging interval)
TotPrcp: total precipitation measured in millimeters (mm)
CumPrcp: cumulative precipitation measured in millimeters (mm)
TotSoRad: total solar radiation measured in watts per square meter*

*TotSoRad is an optional SWMP supported parameter

Nutrient and Pigment Data

Nutrient and pigment data are collected from at least the four fixed water quality stations within or adjacent to the Reserve on a monthly basis.

Parameters and Units*

PO4F: orthophosphate measured in milligrams per Liter (mg/L) as P
NH4F: ammonium measured in milligrams per Liter (mg/L) as N
