Аннотация:

Трассовый Фурье-спектрометр инфракрасного диапазона использовался для обнаружения и мониторинга концентраций основных газов, загрязняющих атмосферу, в центре Мехико. Модулированный пучок инфракрасного излучения со спектральным разрешением 0,5 см-1 передавался и регистрировался парой телескопов Кассегрена, проходя горизонтально в атмосфере расстояние 426 м. Концентрации восстанавливались на основе анализа спектра с использованием обычного метода наименьших квадратов при сравнении зарегистрированного спектра (при его наличии) и синтетического спектра в качестве эталонного. Представлены результаты измерений, полученные в феврале 2002 г. Впервые приводятся распределения концентрации ацетилена, этилена, этана, пропана и метана для исследуемого региона с высоким временным разрешением. Наряду с результатами изме-рений приведены метеорологические данные, на основе которых построена роза ветров и определены возможные общие источники этих соединений.
