Stationary Rolling Average Update

Changes made:

1. Runtime Optimizations
2. LDAR-Sim Run scripts were refactored to shared common behavior and be more modular
3. Added LDAR-Sim error logging functionality
4. Added parameter to keep all program outputs
5. Added parameter to disable pre-simulation emissions
6. Updated Stationary Rolling Average functionality
7. Various bugfixes:
   • Fixed runtime error during emissions creation when duration is provided in infrastructure files
   • Fixed METEC NoWind sensor
   • Fixed runtime error occurring in scenarios with little detected emissions
   • Fixed runtime error occurring when simulation duration was <= 1 year

v4.1.0 Release

Includes the functionality of duration estimation based on a user provided factor - See the User Manual for more details

Version 4.0.0 Release

Introducing LDAR-Sim version 4.0.0!

LDAR-Sim version 4.0.0 is a complete refactor of LDAR-Sim, including introducing an all-new sensitivity module and new uncertainty outputs, improvements to how the virtual world is modelled, an overhaul of the scheduling algorithm, and more...

Key Features

• Improved User Manual
• Improved stationary deployment - continuous monitoring is now based on rolling averages
• Improved quantification error
• Refactored emissions, added granularity - see User Manual for more details
• Refactored infrastructure, added granularity - see User Manual for more details
• Refactored sensors, the following sensors are now built into LDAR-Sim: METEC_NoWind, OGI_Zim, and OGI_RK (See user manual for more details on how to use them)
• Refactored scheduling, significant runtime improvement from v3
• New Output parameters to disable outputs
• New uncertainty outputs
• New Sensitivity Analysis Module
• New debugging mode - enables benchmarking

And more!!

Special Thank You

Special thank you to the Colorado Department of Public Health and Environment(CDPHE) for supporting and funding the development of version 4.0.0 of LDAR-Sim.

v3.3.0 Release

Includes a key bugfix for follow-up: proportion.

V3.2.0 Release

Release for V3.2.0 introducing new flags to enable/disable LDAR-Sim outputs separately

v3.1.0 Release

The virtual world parameter n_init_leaks was reworked to n_init_leaks_prob. See the User Manual for more details

v3.0.0 Release - Simplified Parameters

LDAR-Sim parameters have been changed to be simplified such that a single virtual world can be constructed to model sites and emissions for a set of programs in the model.

V2.4.0 Release

What's new: the subtype_time_file was removed due to poor behavior.

Customization of leak initialization

New Feature: Users are now able to provide their own inputs to initialize the number of leaks and potential setup duration for the initial leaks in the simulation

External Sensors

Example external sensors, documentation and guidance on how users can generate their own is now provided.
