Release notes

Release note (v.4):

- Integration of TrajResult to quantitavely evaluate the influence of a selected zone. Added automatic edge detection over a specified zone

- Integration of residence time calculation from a selected zone to the receptor site

- change size of NWR graph

Release note (v.3.70):

- Debugged data filtering for WS_std and WD_std for SWIM and SWIM-2    

- Warning if Igor 7

- pop up buttons for each graph on the Explore panel (Improvement added by L. Poulain)

- Boolean summary of trajectory options displayed after each run.

- //advanced users// manual possibility to account for the uncertainty of trajectory, by inserting an increasing 2-D Gaussian noise along trajectory.

Release note (v.3.60):

- Openair calculation available. ZeFir controls the Polarplot function through automated R scripting.

Release note (v.3.50):

- Added the license agreement before building ZeFir Panel

- Trajectory maps are scaled, and have fixed height

- added Compare Maps: new panel to compared two trajectory analysis maps.

- New Re-weight procedure

- Debugged the trajectory option where traj is ignored if ending altitude is above PBL

- State and Province boundaries are downloadable from ZeFir website. DOWNLOAD

Release note (v.3.40):

- Debugged MS calculation with CF

- added possibility to ignore backtrajectory if it ends above PBL

- Hooked all windows to ZeFir main panel

Release note (v.3.321):

- Debugged SafeChecks which caused calculation abortion

Release note (v.3.32):

- Check for update in the ZeFir Menu

- Debugged cluster analysis

Release note (v.3.31):

- font and fsize parameters added to all interactions in order to prevent changes of display from a computer to another.

- replaced error messages in the history by Doalert panels.

Release note (v.3.30):

- added a supplementary & independant module to calculate backtrajectories from a simplified panel which controls the scripts provided in the HYSPLIT software package. So far, only GDAS file can be used. Further improvements will follow.

Release note (v.3.20):

- added cluster analysis. Calculation is done through the HYSPLIT scripts (the PC-based version of HYSPLIT is mandatory. Click here for more information).

- added possibility the explore backtrajectories directly in ZeFir, or from a standalone panel. They can be color-coded by date, altitude, or concentration.

- minor bug concerning cutoff option by precipitation. Rain column wasn't found if precipitation is the only additionnal meteo. parameter.

Release note (v.3.11):

- added continuous weighing function for trajectory analyses (sigmoid-like function). Weighing coefficients can be calculated from 3 parameters only instead 7 with a regular discrete function. More details included in the manual.

Release note (v.3.10):

- added possibility to use 2-D matrices as input data. In this case, ZeFir aks the user to provide the column number to use.

- added possibility to use calculated percentile values for concentration & ext. var. min & max thresholds. For example, to use the 10th percentile, type "p10"

- added possibility to perform automatic seasonal calculations for all seasons in one run. Be careful: the 4 seasons need to be present in the dataset, otherwise errors are expected.

- added SWIM & SWIM-2 methods for wind analyses.

- added pollution roses

- optimized user interface
