| Version | Published | Release Notes | Action |
|---|---|---|---|
| 2.2.0 | deprecated stdatmo function (use atmos instead) |
||
| 2.0.0 | stdatmo superseded by atmos (stdatmo still included in package because of slightly different input syntax).
|
||
| 1.23.0 | minor |
||
| 1.22.0 | capabilities of stdatmodim integrated into main function; documentation and example |
||
| 1.21.0 | Added STDATMODIM wrapper function and updated documentation. |
||
| 1.20.0 | tiny changes to help and input handling; improved vectorization; tested in 2012b |
||
| 1.19.0 | Imperial unit temperature offset now in F/R instead of C/K |
||
| 1.14.0 | fixed error that occurred when using 5 output arguments |
||
| 1.13.0 | Minor changes. Tested in R2010a. Added another example to help. |
||
| 1.12.0 | A bit quicker for troposphere only problems; fixed small units bug. |
||
| 1.11.0 | Added a section such that troposphere-only simple function calls are a bit faster |
||
| 1.9.0 | Final output, Hgeop, changed to ZorH, and is geometric altitude for geopotential input, and geopotential for geometric input. Code made a bit more succinct. |
||
| 1.8.0 | Now substantially faster than earlier versions and ATMOSISA. Cleaned up help and setup for Example 1. |
||
| 1.6.0 | Changed handling of units to be more intuitive and added feature to allow different units for input and output. Earlier version syntax works as before.
|
||
| 1.3.0 | Update to references and improved input handling |
||
| 1.0.0 |
