1. A Dewpoint Climatology in the Capital District of New York
Brian Montgomery & Cameron Paquette

2. Motivation No current dewpoint climatology for our region
Times Union Science Reporter
Many important applications:
Forecasting convection
Wet-bulb processes
Heat indices
Climate Variability

3. Data Records Downloaded NCDC/NCEI surface hourly data
Cities: Albany, Poughkeepsie, Glens Falls
Performed calculations from
Utilized 00z-00z daily timeframe
Questionable observations were removed*
Sub-hourly exceptional high values during convection
Maintenance on instrument
Anomalous observations

4. Could possibly add regression lines to this plot
Could possibly add regression lines to this plot. Might be worth noting where some trends in dewpoint between the three cities are the same or different.

El Nino Years highlighted

6. Albany, NY

7. Monthly Averages
May replace this for Box-and-whisker plots

9. Maxima by Month
As these lack of high values in recent years result of implementation of ASOS?

10. Minima by Month
Notice the same “pattern” does not appear for the minimum's.

11. Albany Seasonal Averages
Blue line is averages taken at each year, black line is the regression

13. Future Work ENSO Correlation Daily Climatology Web Page Development
Expanding to other stations
Possible NCEI and XMACIS implementation?
Additional suggestions?
If there were other things I forgot to mention, feel free to add onto the slides!
