Abstract: A time of day (TOD) synchronizer in a first processor transmits a latency measure message simultaneously on two links to a second processor. In response, the receiver in the second processor detects latency differential between the two links, detects the delay in the second processor, and sends the latency differential and delay to the first processor on one of the two links. The first processor stores TOD delay values in the two links that account for the latency differential between the two links. When a TOD message needs to be sent, a link loads a counter with its stored TOD delay value, then decrements the counter until the TOD message is ready to be sent. The resulting counter value is the receiver delay value, which is transmitted to the receiver as data in the TOD message, thereby reducing TOD jitter between the two links.

Abstract: Post-processing corrections can be applied to operational numerical model forecasts of weather variables to reduce forecast model errors. The post-processing technique is based on an analog post-processing correction scheme. In the analog scheme, the system searches for previous model forecasts that are similar to the current forecast, and modifies the current forecast based on errors in such previous predictions. An “abnormal (or abnormal) index” can be generated for each analog as a function of several meteorology variables (i.e., humidity, pressure and temperature) and two experience coefficients. The abnormal index can be used to exclude some errors. Furthermore, dynamic weights based on the “abnormal index” can be applied to the errors. Using the “abnormal index” weights in a post-processing technique may generate a more accurate air quality forecast.
