Looking for a free and secure messaging app for friends and personal communications?

We recommend Signal.

Signal is a messaging app that recently surged in popularity when it was endorsed by Tesla CEO Elon Musk. What immediately sets Signal apart from Whatsapp and other messaging apps like Telegram and Viber, is that unlike these messaging apps which are backed by major corporations, Signal is a non-profit foundation funded by donations.

Looking for an Internet browser that won't track you or your data?

We recommend DuckDuckGo.

In terms of functionality, DuckDuckGo is a search engine much like Google, Microsoft Edge, and Safari. Looking for something on the internet? DuckDuckGo will be able to find it for you. What makes it different from the major search engines is that DuckDuckGo doesn't track your search history.

Looking for an end-to-end encrypted collaboration platform for business?

We recommend Tauria.

When it comes to a complete and fully secure work collaboration experience, then Tauria is an app that you should definitely consider. Unlike Slack, Microsoft Teams, Google, Zoom, or other similar collaboration apps, Tauria offers a true end-to-end encrypted collaboration platform that features Video Conferencing, Webinars, Messaging, File Storage, and Scheduling functionalities tailored specifically to meet the secure collaboration needs of businesses.

Onsite Data in AERMET - Part 1: Formatting

AERMET – the meteorological pre-processor for the AERMOD modeling system – allows users to input their own custom meteorological data via its Onsite Pathway. This produces a highly representative dataset when using observations recorded at the site that will be modeled in AERMOD. One of the biggest challenges to this approach is that the modeler is responsible for identifying the variables and input format to AERMET. AERMET has two separate format specifications which can be utilized:

  • FORTRAN statements, and
  • FREE format

With FORTRAN statements, modelers tell AERMET the exact format of each line by defining each character (or ‘column’) as a certain character type. For example, I is reserved for integer values like date and time variables. Using a FORTRAN statement of I2 means a two-character integer variable will be read. F is used for floating values which have decimals, so a statement of F10.2 means a numeric value with 10 characters (including the decimal point) and 2 characters that appear after the decimal.

FREE format – also called list-directed data – is read as a list of values which are separated by at least one blank space or a comma. Using this option greatly simplifies the process of identifying the file format structure but requires every single data value be read into AERMET (i.e., you cannot skip any values).

In AERMET View, formatting inputs are specified on the Data Records tab of the Onsite Pathway. The image below shows an example file which is read using the FORTRAN Format option. Since no values were skipped in this observation, the FREE format option could have also been used to produce the same result from AERMET.

Modeling Tip picture

Using FORTRAN statements can be a challenge for modelers not familiar with the FORTRAN language, AERMET View includes a Modeling Tip picture   button which will read the line of data and come up with a suggested FORTRAN statement.

Next month, we’ll take a closer look at rules and guidelines for formatting your Onsite data file.



Will Climate Change Outpace Species Adaptation?

March 5, 2021 - Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.
