TAMDAR
GLFE User Survey
I. Data Access
1. Via what means do you prefer to display and examine TAMDAR data?
AWIPS (NWS only) FSL Java Website Both I have not examined TAMDAR data No Response
Comments:
2. Are you ingesting and displaying the TAMDAR data in AWIPS?
Yes No No Response
If no, please briefly explain
II. Data Forecast Utility and Usefulness
3. How would you rate the timeliness of the TAMDAR data available in/near your CWA?
Excellent (always data available when needed) Good Adequate Not adequate (would like to see more frequent soundings if available) Poor (Data hardly ever available when needed) No Response
4. How would you rate the spatial distribution of the data in/near your CWA?
Excellent Good Adequate Not adequate (and my location is No Response
5. Has the TAMDAR data helped to improve the quality/accuracy of warnings and forecasts at your office?
If yes, please briefly describe how it has been most useful:
6. How would you rate the overall utility and usefulness of the data in forecasts and warnings?
Excellent Useful in most situations Good Useful in many situations Fair Useful in a few situations Poor - Not very useful Have not had enough opportunities to evaluate yet No Response
III. Data Quality
7. How often do you encounter bad TAMDAR data?
Almost never (<1% of the time) Rarely (1% to 10% of the time) Occasionally (> 10 % to < 25% of the time) Frequently (> 25% of the time) Dont Know No Response
8. Have you found the TAMDAR data quality to be comparable to RAOBS and ACARS data?
9. When you encounter a questionable/suspect TAMDAR sounding, the problem is usually related to:
Too much missing data (T, Td and/or winds) Temperature Profile Moisture Profile Winds Icing events Turbulence events No Response
10. Please rate the usefulness of the following measurements on a scale of 1 to 5, with 5 being the most useful:
5 4 3 2 1 No Response Temperature 5 4 3 2 1 No Response Moisture (RH or Td) 5 4 3 2 1 No Response Winds 5 4 3 2 1 No Response Turbulence 5 4 3 2 1 No Response Icing 5 4 3 2 1 No Response GPS altitude
11. When you encounter a suspect or questionable sounding, how do you deal with it?
Investigate further by comparing to other data sources (e.g., other TAMDAR/model soundings, satellite/radar, etc). Examine another TAMDAR sounding if available. I just assume the data is bad and stop looking at it. Ask a question on the TAMDAR forum Report it to AirDat I dont have time to investigate suspect data further. No Response
12. Would you like to see the high density TAMDAR data (i.e. 10 hPa data) extend to higher than 100 hPa above the ground?
Yes (if yes, how high?) No No Response
13. Because TAMDAR was installed on aircraft flying to smaller/regional airports for the GLFE, sounding data is usually not available above 600 mb . Do you consider this to be a hindrance to using the data operationally?
No, the data is still very useful in most situations. No, I usually can supplement with other data sources (ACARS, RAOBS, model soundings etc) Yes Dont Know No Response
14. How would you rate the overall quality of the TAMDAR data?
Excellent Good Fair Poor No Response
15. How would you rate the overall usefulness of the TAMDAR data?
16. Could the TAMDAR data be presented in another form that would make it easier to use or more useful to you?
IV. Miscellaneous
17. Do you feel you have adequate time to examine the TAMDAR data on shift?
Always Usually Sometimes only look at during active weather situations. Sometimes only look at when I have time. Not really No Response
18. How likely are you to examine TAMDAR data in the future?
Plan to examine the data all the time Plan to examine only in certain weather situations Plan to examine only if I have time Do not plan to examine the data No Response
19. Have you reviewed the TAMDAR Training CD?
Any Additional Comments?
