August 9-12, 1999
The URSI/COSPAR Working Group on the International Reference Ionosphere (IRI) will hold its next annual meeting at the University of Massachusetts Lowell, USA, from August 9 to 12, 1999, i.e. in the week preceding the URSI General Assembly in Toronto, Canada. These annual meetings are the primary venue for improvements and refinements of the IRI representation of ionospheric electron density, electron temperature, ion composition and ion temperatures.
The special emphasis of the 1999 Workshop will be on (1) specification of the variability of ionospheric characteristics, and (2) the use of IRI for ray tracing studies and applications.
Other topics of interest for the workshop include comparisons of IRI with measurements and with other models, suggested improvements and additions for IRI, and applications of the IRI model. Papers on new additions to IRI are especially welcome: strom-time model, ion drift model, spread-F model, and plasmaspheric model. It is expected that selected papers from this meeting will be published in Advances in Space Research.

Airport Transportation
For transportation from Logan Airport (Boston) to Lowell, we recommend two services. Both services are clearly marked on the outside of each bus/van:
One service is M&L Bus Line. To schedule a pick-up with this service, on arrival in Logan, use a pay phone and call 1-781-938-8646. The cost of the call will be $0.25. Advise the M&L operator what airline you arrived and that you want to go to the DoubleTree Hotel in Lowell. They will advise you when the next shuttle arrives and where to meet the shuttle. The cost, cash or travelers checks, is $22 for one or $34 for two people plus gratuity (typically 10 - 15% based on quality of service). This bus/van will bring you directly to the DoubleTree Hotel in Lowell. To get from the hotel to the dormitory, you will need to take a taxicab to Donahue Hall (North campus) at the University of Massachusetts Lowell. This ride is approximately 5 km. The front desk at the hotel can assist you in getting a taxi.
Another service is Flightline, however this service requests a twenty-four hour advance notice, specifically if you are arriving in Boston after 11:00P.M. We will assist you in making a reservation should you decide to use this service. Once a reservation has been made and you arrive in Logan, to schedule a pick-up, use a pay telephone and dial 1-800-245-2525 (this is a free call). Again advise the operator with which you arrived and that you want to go to the DoubleTree Hotel in Lowell. They will advise you where and when to catch the next shuttle. The cost, cash or traveler check, is $29 for one person, $45 for two people plus gratuity. As above, this bus/van will take you directly to the DoubleTree Hotel. Again to get from the hotel to the dormitory, you will need to take a taxicab to Donahue Hall (North campus) at the University of Massachusetts Lowell.
Local Lodging
Two local lodging arrangements are available to the IRI participants. The first is the local DoubleTree Hotel Lowell, located in downtown Lowell approximately 3 km from our facility. The charge per night is $97.63 (this includes all taxes) and you can charge your room on a credit card. The telephone number is (978) 452-1200 (or 800 876-4586 in the Continental U.S.), facsimile (978) 453-4674. If you elect to make your own room reservations, please advise the reservations clerk that you are part of the University of Massachusetts Lowell Center for Atmospheric Research IRI Workshop, as we have reserved a block of rooms for participants. This block of rooms is only reserved through 16 July 1999, so reservations must be made before this date to ensure room availability. If you advise us of the date and approximate time you will be arriving in Lowell, we will make your room reservations for you. If we are making the reservations, please let us know if you will have a traveling companion (the room rate is the same for two people per room) and if you desire a smoking or non-smoking room. If we make the reservation for you, we will need a credit card number to confirm the reservation. You will not need a rental car as we have made arrangements with the hotel for daily shuttle service to/from the University for each day of the workshop. The hotel has one restaurant, room service and one lounge operating on the premises.
The second lodging option is the University dormitory. We have made arrangements with one of the dormitories for lodging. The rate for the lodging is $100 per week (workweek) per person. Additional costs may apply if you stay in the dormitory over the weekend. Housing will be guaranteed through 1 July 1999, then will only be available on a first-come-first-serve basis. Payment can only be done with cash or travelers checks. Each room is equipped with a phone offering free local calls and a voice mailbox. An initial linen package will be included at no additional cost. Washers and dryers are available in the building. There is cafeteria service operating across the street offering three meals a day. Meals are not included in the room rate, however, are very affordable. The dormitory is very close to the Conference Center, approximately 0.25km.
In order to check-in to the dormitory, you will need to obtain your key and key pad code from the Wannalancit Security Office located at 660 Suffolk St., Lowell, MA. Please make sure the taxi takes you to this location first. This office is located approximately ½ a mile from the dormitory. Along with your key you will receive a map with directions to the Donahue Dormitory. You will need to provide the Security Office with identification in order to receive your key. Also, they will not allow you to pick up someone elses key on their behalf. The Security Office is open 24 hours a day so there will be someone there no matter what time you arrive. Please be aware that I will be collecting the money for your accommodations the following day you arrive. Upon departure you should leave the key in your room, preferably in the envelope.This year we will have access to one of the newer dormitories at the University for the lodging, however, the dormitory is not air-conditioned. Fans are available, as long as their supply of fans lasts.
Conference Facilities
The conference facility for the IRI Workshop will be the MIL Conference Center located in the Wannalancit Mill Complex at 600 Suffolk Street (the same building as the Center for Atmospheric Research). The MIL Conference Center is approximately 5000 ft2 equipped with state-of-the-art presentation equipment. A summary of equipment available includes:
