PsyCalc® Binner is a
veritile tool for binning hourly weather data using two
methods with multiple bin variables and bin sizes.
Create Conventional bins against dry bulb temperature,
wet bulb temperature, humidity ratio or dew point
temperature. Or use Joint Frequency binning which
tallies hours in a grid of dry bulb temperature and
You will need a FULL license to gain access
to hourly data for 4,109 locations worldwide. The BASIC license allows
access to only a small set of Sample Locations. For instructions on downloading
hourly data files see Download Hourly
PsyCalc® is offered at
two licensing levels, basic and full. The basic level
allows use of a Sample Locations database with locations
from many regions around the world. With a full license
PsyCalc® users have the option to download and install
databases for nine(9) regions around the world for a
total of over 4,100 locations. Each region has its own

a preset schedule of hours to include. Manage your own
schedules with the New, Update and Delete buttons.
Conventional creates bins for the selected psychrometric property (Bin on) with the selected bin size (Bin size).
Joint Frequency creates a grid of
dry bulb temperature (°F / °C) / humidity ratio (gr/lb /
g/kg) bins of the size specified. (See output examples
Use the Select Mmonths list and the hour lists for each day of the week to define your schedule.
Selections made in the All list
affects all days of the week.
With the binning type and
schedule defined click the Create Bins button at the

An IMPORTANT note about Weater Data Files
All weather data file supplied with PsyCalc® are derived
from "Typical" weather data sources. Here "Typical" means that the producer of
the data file has analyzed many years of data and compiled full years (8760
hourly records) using the most typical of each month for the location from the
many years available. The data producers make minor adjustments as necessary at
month boundaries so that the data represents a normal diurnal pattern. Each
record includes the date of the original data. As you can imagine ajacent months
are most likey not from the same year making day of week values calculated from
the actual record date non-contiguous. For example the TYM3 raw data for
Colorado Springs, CO, USA uses January data from 1991 and February data from
1990. Using the actual record dates to calculate day of week would give us January 31 as a Thursday and February 1 also as a Thursday.
When Linric Company compiles data files for PsyCalc® we ignore the actual dates assigned to each
record, assign Sunday as the day of week for January 1st and proceed sequentially with day of week assignments.
Using this method data for all locations start on Sunday and end on Sunday. This allows the comparison of results
from multiple locations regardless of the number of hours included in the schedule. Care should be taken when comparing
results from PsyCalc® binning and other binning tools as other tools may not have used this same day of week assignment philosophy.
