Web-based Reanalysis Intercomparison Tool: Vertical Profiles of Reanalysis Datasets

Select a date, location and a dataset. Choose from vertical profiles, vertical transects and height by time plots. For profiles, you will also get a table of the atmospheric variables for that date or range of dates (caveats).

Plot Type:   Vertical Profile(s)     Skew T     Vertical Transect     Height by Time
Variable:     Top Analysis level?
Reanalysis Dataset:   NCEP/NCAR R1 20CRV2c 20CRV3 ERA-Interim  
Latitude: Longitude: (use 0-360)

Year:    Month:  Day:     Hour (UTC):    
For multiple profiles or time by height plots enter last date of range.
Year 2:   Month 2: Day 2:   Hour 2 (UTC):  
If time by height plot or transect:
Mean Anomaly
Change default contour range/interval
Low: High: Interval:
Contour lines? No Yes
Aspect Ratio (X/Y) timexheight
For a transect along a line, enter 2nd lat/lon value.
