mdv-climex's Issues

Wind roses and averaging

A challenge with using a daily average wind speed for wind roses is you end up with a direction that is not realistic. Bonney is a great example. The two dominant wind directions are NE and SW (and these switch daily). As a result, your daily wind rose is from the SE (which doesn't reflect a real wind direction). Example below:

wind_BOYM.pdf

To correct this, a mode wind direction might make more sense if you want to stick with daily data.

Clarify RH heights

  • App pulls air temperature heights from EDI entity column names.
  • RH is sometimes measured at multiple heights.

Fix unit formatting

E.g., m^2 should be m2
E.g., W/m^2 should be W m-2

Additionally, remove units from plotly titles, as listing the units in the y-axis suffices.

Merge CAAM 2m and 3m airtemp

Sensor was moved from 2m to 3m in the middle of the time series. Merge for easier viewing and historical comparison.

Exclude CAAM_PRESSTA

Data were only provided for one season and the data format is not app-friendly. So, the app shows it as an option at CAAM, but there aren't any data to display.

Bug in parameter selection when new met station is selected

In app.R, add code in section "# Update choices when a new met station is selected" to address a bug that occurs when a user has selected a particular parameter suite, e.g., EXEM RADN, then selects a new station that does not have this parameter suite, e.g., FRSM. When this occurs, the app crashes with the following error: Warning: Error in : '../data/FRSM/FRSM_RADN/FRSM_RADN.csv' does not exist in current working directory...

Exclude netrad from BRHM, CAAM, FRSM

Only one season of netrad data from BRHM and CAAM, and should be excluded. Although a full record exists at FRSM, it should be excluded from the app for simplicity, which means that RADN should be excluded from FRSM, since no other solar radiation data are measured at this site.

Improve wind rose visualizations

Explore use of windRose() in openair and other libraries to improve wind rose visualizations. Current package does not allow for customization of wind speed bins, etc.
