What a Cybersecurity Breach Will Cost You in 2021

Global experts predict that cybersecurity breaches will cost the world $10.5 TRILLION annually by 2025.

On average, the cost of a single data breach has reached $200,000. This means that a mere “average” cybersecurity attack could potentially put a company out of business. In fact, sixty percent of small companies go out of business within six months of an attack.

If you’re a small-to-medium business, recovering from a cyber attack will cost you roughly $13,000-$38,000. And this does not account for lawsuits and damage to your company’s reputation. Small businesses have, unfortunately, also become more common targets of cyber attacks, accounting for a whopping 43%-47% of cyber crimes.

If you are an enterprise level company, the cost to recover from a cyber attack can exceed $1M.

How can I defend myself against a Cyber Attack?

The best way to defend yourself against attack is through prevention.

Going after cyber criminals after a breach has occurred is a lot like trying to un-spill milk or un-tell a secret. Even if you do manage to track down and make the criminals pay back whatever monetary value the breach cost you, the proprietary and highly sensitive information that was leaked can never be taken back.

The breach can result in ruined reputations, possible lawsuits against your company, and the loss of your competitive edge. For most companies, this kind of damage cannot be mitigated, adding to the growing number of failed businesses.

As mentioned, prevention is the most important step your company can take, and the first step must be to secure all your business communications including video conferencing, webinars, messaging, and file sharing.

Working with Different Model Versions in AERMOD View

Numerous versions of the AERMOD model have been released over the years. These updates include new algorithms, enhancements to existing features, bug fixes, and more. New model versions are published by the US EPA to the Support Center for Regulatory Atmospheric Modeling (SCRAM) website. In the United States, the newly published model officially becomes the preferred version of the model.

There are many situations where a modeler may wish to use an older version of the AERMOD executable. For example:

  • Regulators in some countries may still mandate the use of an earlier version of AERMOD.
  • A specific version of AERMOD may be stipulated in the modeling plan and permit application, even though a newer version of the model may have become available since the project started.
  • There are certain situations where a custom recompiled version may be required to support specific non-regulatory options or to implement advanced modeling configurations such as the ability to run in a parallel processing environment.

The newly released AERMOD View Version 10.0 supports the latest U.S. EPA AERMOD model update (version 21112). It also supports backwards compatibility for AERMOD versions dating back to 2012 (version 12345). To change the version of AERMOD used by the interface, complete the following steps.

Step 1: Open the File menu and select Preferences.

Step 2: The various models available in AERMOD View are listed under the EPA Models/Limits section. Select AERMOD.

Step 3: The default executable is AERMOD.EXE which represents the 32-bit version of the most recent US EPA executable (currently 21112). Since the version 18081 release, the EPA has included both 32-bit and 64-bit compilations of the model. If your computer runs a 64-bit operating system, you can choose the X64 model.

Select the drop-down list to see all available model executables.

Step 4: Select the version of the model you want to use. Executables named AERMOD_MPI_LAKES_xxxxx.EXE represent the parallelized version of the listed model number. This version is developed by Lakes Software and is included free of charge for AERMOD View users who have a computer with multiple processors (see installation instructions for further information).

Note that the selected version is ‘sticky’. You will continue to run with the selected executable until the next time a change is made.

Step 5: Users can also select their very own recompiled version of AERMOD by selecting the User-Specified radio button. Use the Browse button Modeling Tip picture to search your computer for the desired executable. When modeling with a User-Specified executable, it is the user’s responsibility to verify all the proper model options are selected.



Warmer Clouds, Cooler Planet

June 7, 2021 - Today’s climate models are showing more warmth than their predecessors, forecasting an even hotter future for the same rise in atmospheric carbon dioxide. But a paper published this week highlights how models may err on the side of too much warming: Earth’s warming clouds cool the surface more than anticipated, the German-led team reported in Nature Climate Change.

NOAA, Boeing Team Up to Test Greenhouse Gas-Measuring Technology

June 3, 2021- NOAA and Boeing are teaming up to evaluate the best placement for a NOAA greenhouse gas sampling system on a commercial jet by testing options on a new Boeing 737 as part of Boeing’s 2021 ecoDemonstrator flying test bed program. This is a first step toward an expansion of NOAA’s global atmospheric sampling network to include commercial airliners in the U.S. and International airlines in these critical data-gathering efforts.
